Application of unilateral biportal endoscopy technique to resect a thoracic spinal intradural extramedullary meningioma: technical report and review of the literature

BackgroundMeningiomas are common intradural extramedullary spinal tumors, which arise from arachnoid cap cells in the leptomeninges surrounding the brain or spinal cord. Sensory and motor dysfunction as well as pain were the most common presenting symptoms. Surgical resection remains the primary treatment for spinal intradural extramedullary meningiomas. Traditionally, spinal meningiomas excision requires longer skin incision, bilateral subperiosteal muscle stripping, and total laminectomy. We report a new technique for the treatment of thoracic spinal intradural extramedullary meningioma, which involves the use of unilateral biportal endoscopy (UBE) technique to resect the tumor, and reviewed and analyzed relevant literature.Case presentationA 69-year-old female patient presented with back pain accompanied by slowly progressive lower limb paresis, and severe pain in the right lower limb. Magnetic resonance imaging suggests a thoracic spinal intradural extramedullary meningioma. She underwent meningioma resection using UBE technique with complete recovery at the follow-up examination 3 months after surgery.ConclusionThis case confirmed the UBE technique can be a good choice for resection of spinal intradural extramedullary meningioma.

TCL1-family negative T-cell prolymphocytic leukemia with rapid progression of extranodal disease despite a normal white blood cell count

Here we describe the case of a 69-year-old man who was found to have moderate thrombocytopenia and severe splenomegaly during a medical checkup at the age of 67. At the first visit, his white blood cell (WBC) count was 7,400/µl with 80% lymphocytes, and bone marrow aspiration showed 24% atypical lymphocytes. Flow cytometry of atypical lymphocytes was positive for mature T-cell markers, and T-cell clonality was revealed by T-cell receptor gene rearrangement. TCL1 was negative on immunohistochemistry. We diagnosed TCL1-family negative T-cell prolymphocytic leukemia (T-PLL) and employed watchful waiting. Thirty months after diagnosis, the patient developed urinary retention and right lower-limb paresis despite a normal WBC count, and an extradural tumor around the thoracic vertebrae and spinal cord compression were detected. The tumor was diagnosed as extranodal involvement of TCL1-family negative T-PLL, but the patient's general condition deteriorated rapidly, and no treatment was possible. T-PLL is a rare disease characterized by leukocytosis, and the WBC count generally increases with disease progression. Although blood counts are recommended for observation, it is important to keep in mind that the disease may worsen even if blood counts do not change.

Why do we so rarely recognise and treat the primary progressive form of multiple sclerosis?

The primary progressive form of multiple sclerosis is characterised by a systematic increase in disability from the onset of the disease, usually without overlapping relapses. It is estimated that it accounts for 10–15% of all cases of multiple sclerosis, occurs with similar frequency in both sexes, and its symptoms appear at an older age, usually after 40. The initial manifestation usually consists of pyramidal symptoms and myelopathy. The most typical symptoms include progressive gait and sphincter function impairment. Symptoms of cerebellar syndrome, truncal syndromes, as well as visual and cognitive disturbances are less common. The clinical course with characteristic symptomatology resulting from the location of the changes primarily in the spinal cord, followed by the occurrence of initial symptoms, means that this form of multiple sclerosis requires careful differential diagnosis. It should be differentiated primarily from diseases causing lower limb paresis (myelopathy associated with vitamin B12 deficiency, amyotrophic lateral sclerosis, spinal cerebellar ataxia, neuromyelitis optica spectrum disorder, Wernicke’s encephalopathy, Lyme disease, and spinal cord tumours). The diagnosis of primary progressive multiple sclerosis should be guided by the current 2017 McDonald diagnostic criteria. Understanding these criteria and being aware of the differences from the most common relapsing-remitting form of multiple sclerosis can be helpful in speeding up the diagnosis and implementing effective treatment. Even though new treatment options have emerged in recent years, primary progressive multiple sclerosis is still little known and too rarely recognised.

Paretic complications of tick-borne encephalitis and Lyme neuroborreliosis in the Czech Republic: Characteristics and clinical outcome

Tick-borne encephalitis (TBE) and Lyme neuroborreliosis (LNB), the most common tick-borne diseases of the central nervous system in Central Europe, are frequently associated with pareses. The aim of this study was to characterise paretic complications in patients with TBE and LNB, including their severity, persistence and impact on the patients' quality of life. Our retrospective observational study included patients with aseptic CNS infection due to TBE virus or Borrelia burgdorferi sensu lato. Paretic complications were evaluated in the acute phase and the patients were followed up until complete regression or long-term stabilisation of any neurological deficit. The severity of the neurological deficit was graded according to the modified Rankin Scale (mRS).A total of 823 patients (582 with TBE, 241 with LNB) was included. Paretic complications were diagnosed in 63 TBE patients (10.8 %) and in 147 LNB patients (61.0 %). In TBE, the most common neurological deficit was brachial plexus paresis in 21 patients (33 %) and bulbar symptoms in 18 patients (29 %). In LNB patients, facial nerve palsy was the most frequent neurological deficit (117patients; 79.6 %), followed by lower limb paresis in 23 patients (15.6 %). Forty-nine TBE patients and 134 LNB paretic patients completed follow-up. Paresis resolved within 3 weeks in 16 TBE patients (33 %) and 53 LNB patients (39.5 %), but the proportion of patients with paresis persisting for more than 12 months was significantly higher in TBE (34.7 vs. 3.7 %, p < 0.001). The mean mRS was significantly higher in TBE paretic patients compared to LNB (p < 0.001).Paretic complications are significantly more common in LNB than in TBE but pareses associated with TBE last longer than in LNB and considerably reduce the quality of life of patients. Prevention remains the only way to influence the long-term motor deficits of TBE.

A microprocessor stance and swing control orthosis improves balance, risk of falling, mobility, function, and quality of life of individuals dependent on a knee-ankle-foot orthosis for ambulation

Introduction The C-Brace microprocessor stance and swing control orthosis was designed to overcome safety and functional limitations of traditional knee-ankle-foot orthoses (KAFOs) for individuals with lower limb paresis. However, a systematic comparison to established KAFO types has not been performed in a bigger sample. Methods International multicenter, randomized, controlled, cross-over clinical trial. Legacy KAFO users at risk of falling were randomized to KAFO/C-Brace or C-Brace/KAFO use for three months with each orthosis. Primary outcome was balance assessed with the Berg Balance Scale (BBS). Secondary outcomes were falls, mobility, function, and quality of life. Results Intention-to-treat analysis with 102 participants. With the C-Brace, the BBS improved by 3.3 ± 6.3 points (p < 0.0001). Significantly fewer participants presented BBS scores <40 indicative of increased fall risk (16 vs. 36, p = 0.018). Mean falls reduced from 4.0 ± 16.8 to 1.1 ± 3.3 (p = 0.002). Outcomes for function, mobility, and quality of life showed significant improvements with the C-Brace. Discussion The improvements in fall risk and mobility can be attributed to the stumble recovery and controlled knee flexion during weight bearing of the C-Brace and have a positive impact on the quality of life of users. Conclusion The C-Brace represents an option for KAFO users with increased fall risk and reduced mobility.

Adapted Portuguese folk dance intervention for subacute rehabilitation post-stroke: study protocol.

Dance can be an innovative, well-accepted, and effective therapy for stroke survivors. The present protocol aims to assess the feasibility of adapted Portuguese folk dance as a post stroke rehabilitative activity. We will use a mixed-methods pilot study convenience sampling to recruit 16 stroke survivors with mild-moderate lower limb paresis from a rehabilitation center in Lisbon and Tagus Valley. In addition to usual care, participants will attend 3 days per week 1-h dance exercise for 8 weeks. The dance style used for this intervention will be an adaptation of the Portuguese folk dance. Assessment will be conducted before and immediately after the program intervention. Acceptability will be assessed by four key domains (enrollment, retention, satisfaction, and recommendation to others). Safety will be assessed based on the number and type of adverse events. Feasibility will be assessed based on balance performance and functional mobility. Quantitative data will be analyzed through descriptive statistics for sample characterization, followed by inferential statistics to evaluate differences in the balance recovery and functional mobility scores between the initial and final assessment. Qualitative data will be analyzed using an inductive process of content analysis. The Portuguese folk dance program has the potential to improve balance outcomes and functional mobility. Our results will help validate Portuguese folk dance as a tool for rehabilitation settings for stroke survivors. The potential of our program to enhance balance outcomes and functional mobility among stroke survivors bears implications for aging and public health initiatives. Positive results from this study could pave the way for integrating dance-based rehabilitative activities into standard stroke rehabilitation protocols, catering to older stroke survivors' specific needs and preferences.

Abstract TP68: Experiences Of Community-dwelling Stroke Survivors With A Virtual Multidisciplinary Stroke Clinic During The Covid Pandemic

Background: Past research has supported the benefits of dance in improving balancing and walking ability in people with neurological conditions. More evidence on stroke survivors’ satisfaction and perceived benefits of dance interventions on their recovery is needed. Purpose: This study explored the experiences of participating in a virtual ballet-adapted dance intervention among people with lower limb paresis after a stroke. Methods: A qualitative study was conducted with a convenience sample of stroke survivors with unilateral paresis recruited from a support group. The participants attended a virtual dance intervention and learned to perform simple ballet-adapted moves in a sitting or standing position. They then danced together in a group with a Cantopop song of the 80’s. The ballet-adapted moves were designed to improve survivors’ range of motion and control of the joints at ankles, knees, hips, shoulders, and elbows. The participants were interviewed individually after the group dance about their satisfaction with the dance experience. Interview data were transcribed verbatim and analyzed thematically. Results: Fourteen stroke survivors (mean age=62.79 years, SD=9.35) were recruited. Nine of them (64%) walked with a stick. The mean duration after stroke was 10.64 year (SD=8.71). The survivors agreed that the ballet-adapted moves could be performed safely at home, and it was particularly helpful during the coronavirus pandemic to engage them in physical activities. They appreciated the integration of familiar songs in the dance and the group dance experience, which was interesting, easier to memorise the steps, and offered them opportunities to meet people. The experience of mastering new dance moves and working towards a group goal conveyed a sense of accomplishment after stroke. No adverse events were reported during and after the dance. Conclusion: The stroke survivors were satisfied with the virtual ballet-adapted dance intervention. Further studies to investigate the effects of the intervention on improving survivors’ physical and psychosocial outcomes are needed.

Caster Walker GAIT Trainer (CGT): A robotic assistive device

Stroke has become one of the leading causes of lower limb paresis. Costing the patients, a fortune for its diagnosis and prognosis. Clinical experimentations have proven that one can regain ambulation if the rehabilitation is started in the acute or sub-acute stage. Traditional mode of rehabilitation include manual therapies which are labor-intensive and time consuming. Therefore, robotic training are preferred over manual therapies. Nevertheless, there are some limitations such as devices are bulky and complex, some are not portable, others need body weight support system, and costly. To address such issues, this paper proposes development of a new Caster Walker Gait Trainer (CGT) for gait rehabilitation. CGT is an end-effector based passive device in which Stephenson III six-bar linkage has been implemented to mimic the kinematics of a healthy gait. The trainer device uses a belt-pulley system for providing motion to the linkage. The lower limb of the patient gets the drive as he/she pushes the cater walker forward or backward. The paper also proposed the optimal design of defect-free Stephenson III six-bar linkage using loop-by-loop approach. To design the linkage, an optimal problem is formulated, and tear drop ankle trajectory is desired. The optimization problem is solved using a nature-inspired algorithm and it is found that the trajectory generated by the synthesized mechanism is able to mimic the desired trajectory. Then using the notion of inverse kinematics, hip and knee trajectories are obtained from the generated ankle trajectory for validation.

Microsurgical repair of severed thoracic spinal cord and clinical outcome: technical case report

BackgroundThis report describes a case of successful repair of severed thoracic spine in a young man who presented with a penetrating stab injury to spine resulting in Brown-Séquard syndrome. Surgical technique and post-operative management is discussed.Case presentationA 34-year-old fit and well healthy man was admitted with a history of stab injury to the thoracic spine at thoracic T2/3 level with ASIA impairment score (AIS) score D with an incomplete spinal cord affecting his left lower limb with complete paralysis and right lower limb paresis with impaired sensation below T6 level to L5. Neuroimaging confirmed a penetrating knife injury traversing the T2/3 level causing hemi-section of the spinal cord confirmed intraoperatively. He underwent an urgent exploratory surgery of his spine and a T2/3 laminectomy was performed to aid removal of the knife. The dura was noted to be contused and severed spinal cord was noted to be severed with associated cord oedema. A microsurgical repair of the severed cord was performed with duroplasty followed by intense neuro-rehabilitation. On a 3 month follow up his AIS score is E with lower limb power is 5/5 bilaterally and he is able to mobilise independently up to 8–10 steps without any supportive aid and with crutches he is independently functional and mobile.ConclusionThis is the first documented case of microsurgical repair of severed thoracic spinal cord secondary to traumatic knife injury. In the management of such scenario, apart from the removal of foreign body, repair of the cord with duroplasty should be carefully considered. The role of spinal neuroplasticity in healing following timely repair of the spinal cord along with intense rehabilitation remains the key. This had resulted in a good clinical and functional outcome with in a 18-month follow up.

Cumulative Risk And Associated Factors For Fall-Related Fractures In Stroke Survivors After Discharge From Rehabilitation Wards: A Retrospective Study With A 6-Year Follow-Up.

ObjectiveTo investigate the long-term cumulative risk and factors associated with fall-related fractures in stroke survivors discharged from convalescent rehabilitation wards.DesignRetrospective cohort study.ParticipantsA total of 786 stroke survivors discharged from a rehabilitation hospital.MethodsData regarding fall-related fractures post-hospital discharge were collected using self-reported questionnaires. The Kaplan–Meier method was used to calculate the cumulative incidence of fall-related fractures, and risk factors were analysed using Cox proportional hazard regression analysis.ResultsOf 1,861 consecutive stroke survivors who had been discharged from hospital, 786 (42.2%) provided information concerning fall-related fractures. Duration from time of discharge to time of collection of questionnaires ranged from 1 to 6 years (mean 38.0 months). The cumulative incidence of fall-related fractures at 1-, 2-, 3-, 4-, and 5-years post-discharge was 4.2%, 7.9%, 10.8%, 12.5% and 13.7%, respectively. Cox proportional hazard regression analysis indicated that female sex (hazard ratio (HR) 1.69) and moderate lower limb paresis (HR 3.08) were significant risk factors.ConclusionThe cumulative risk of fall-related fractures in stroke survivors post-discharge from a rehabilitation hospital was notably high. Intensive preventive intervention should be considered for female stroke survivors with moderate lower limb paresis.LAY ABSTRACTThis study aimed to investigate the risk of fall-related fractures and associated factors in stroke survivors who had been discharged from rehabilitation wards. A questionnaire was sent by post to 1,861 post-discharge stroke survivors to investigate their experiences of fall-related fractures, to which 786 stroke survivors responded. The incidence of fall-related fractures at 1, 2, 3, 4, and 5 years post-discharge was 4.2%, 7.9%, 10.8%, 12.5% and 13.7%, respectively. The presence of moderate lower limb paresis and female sex were associated with 3.08- and 1.69-times higher risk of developing a fall-related fracture, respectively. Intensive preventive intervention should be considered for female stroke survivors with moderate lower limb paresis following discharge from rehabilitation wards.

UNUSUAL PRESENTATION OF A THYROID MALIGNANCY: A CASE REPORT

Cushing’s syndrome is a rare complication of Medullary thyroid carcinoma [MTC] and is due to ectopic Adrenocorticotropic [ACTH] secretion by tumor cells. Cushing’s syndrome presents a challenging diagnostic and management issue in patients with MTC. Entire clinical history, laboratory investigations, microscopic pictures are discussed in detail.

Сomplex rehabilitation of walking function in central paresis of the lower limb using neuroprosthetic technology

Disability after a stroke is most often associated with decreased patient activity due to walking disorder. In case of severe paresis, the function of the limb in the early stages of recovery is advisable to support with the help of partial prosthetics, using methods that provide functional stimulation. The complex treatment of central paresis includes botulinum therapy, which is due to the high incidence of spasticity.&#x0D; Aim: of the study: evaluation of the efficacy of functional electrical stimulation in a complex of multimodal effects in restoring movement in stroke patients with lower limb paresis.&#x0D; Materials and methods: Stimulation and neuroprosthetic methods (Bioness L300) were used as the main therapeutic program of rehabilitation treatment for patients with motor disorders of the lower limb after an ischemic stroke (n = 70). The median period of stroke was 21 [11; 47] days, median age 54 [42; 65] years. Scales and questionnaires were used to assess the loss of strength and volume of movement disorders, spasticity, walking speed and self-care (Medical Research Council Weakness Scale (1981, MRC), Barthel Index (1965), Modified Ashworth Scale (MAS), 10-meter test).&#x0D; Results: The effectiveness of personalized therapy with the use of a neuroprothesis (Bioness L300) in patients in the acute and early recovery period of ischemic stroke was shown. The additional use of botulinum toxin made it possible to eliminate the inhibitory effect of spasticity, which expanded the possibility of using intensive methods of physical rehabilitation. There was an increase in daily activity, walking speed, and the level of self-care of patients in 90 % of cases.&#x0D; Conclusion: The use of a complex of stimulating personalized techniques in the acute period of a stroke is justified and safe. The functional electrical stimulation helps to overcome power paresis, increases the overall level of physical activity of patients after a stroke, motivation for recovery and improves the quality of life.

Symptomatic interdural cerebrospinal fluid collections after surgery for idiopathic spinal cord herniation: illustrative case

BACKGROUNDIdiopathic spinal cord herniation (ISCH) is very rare. Some reports have described postoperative ventral cerebrospinal fluid (CSF) collections in patients with ISCH; however, such collections are asymptomatic in most patients, and there is no consensus regarding whether they are part of the natural history or a complication.OBSERVATIONSA 30-year-old man with ISCH underwent direct closure of a duplicated dura mater. Eight months postoperatively, he developed reworsening of right lower limb paresis and new severe right arm pain and paresis. Three-dimensional magnetic resonance imaging revealed ventral CSF collections, which the authors judged as the responsible lesions. The authors initially considered these collections to be present in the epidural space, extradurally compressing the dural sac and resulting in myelopathy. An epidural blood patch failed; however, a CSF drainage test resulted in dramatic improvement. The authors therefore determined that the CSF collections were located in the interdural space, not the epidural space. A lumboperitoneal (LP) shunt was performed to reduce the CSF pressure. The patient’s symptoms improved immediately postoperatively. He had developed no recurrence of symptoms 6 months after surgery.LESSONSVentral interdural CSF collections after ISCH surgery can cause reworsening of myelopathy and may be cured by a LP shunt to control CSF pressure.

Ten years evaluation of epidemiology- and mortality-related factors in adults and children with Guillain-Barré syndrome in the north of Iran.

BackgroundGuillain-Barré syndrome (GBS) is the main cause of acute and subacute flaccid paralysis in western nations since the eradication of poliomyelitis.ObjectiveThe aim of this study is to investigate epidemiology and mortality characteristics of GBS in the north of Iran.Material and methodsIn this study, the hospital information system (HIS) was used to access each patient’s information. The final 174 cases were examined in terms of age, sex, place of residence, the year of referral, the month of referral, the season of referral, client city, accompanying background disease, and the type of GBS.ResultsThe mean incidence rate in Guilan province was about 0.69 in 100,000 persons, and the case fatality rate was 10.34%. The most reported type of GBS was AIDP (33.90%), and the most common symptom was upper and lower limbs paresis in 65 cases (37%). Respiratory distress (P = < 0.001), complications during hospitalization (P = 0.0001), and ICU requirement (P = 0.001) were significantly higher in dead patients.ConclusionIn this study, the incidence of GBS was higher in men than women and the highest number of cases was in the age group of 60 to 75 years. The significant point was the high-case fatality rate in Guilan province compared to the previous studies. The complications during hospitalization such as respiratory distress, ICU requirement, and underlying disease had a significant relation with the fatality of GBS.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10072-021-05562-y.

Spinal Hemangioma in Pregnancy: A Case Report

Background: Hemangiomas of bone are localized benign tumors composed of fully developed adult blood vessels. Vertebral hemangiomas are present without symptoms in approximately 10% of the population and more common in females. It is usually located in the lower thoracic and lumbar vertebra and are often multifocal. Infrequently these benign lesions may cause local or radicular pain and neurological deficits ranging from myeloradiculopathy to paralysis. The physiological vascular, hemodynamic and hormonal changes in pregnancy act to enlarge a preexisting hemangioma and most of these changes peak in the third trimester. The most important contributing factor is the increase in venous pressure resulting from mechanical obstruction of blood flow from the paravertebral veins into the inferior vena cava by the gravid uterus. Objective: To study the outcome of management of a case of spinal hemangioma during pregnancy. Case report: A 26-years-old pregnant female patient attended the Department of Orthopedic Surgery at the International Medical Center Hospital, Jeddah, Saudi Arabia, suffering from a severe lower limb paresis and loss of sphincteric control and diagnosed with spinal hemangioma. An intervention was done during pregnancy to prevent further complications by decompressing the spinal cord. Post-delivery, the main surgery was performed to prevent the recurrence. Conclusion: The management of spinal hemangiomas in pregnant women can be done in the following two steps. The First step is short-timed, less bloody intervention to decompress the mass to prevent further damage and complications. The second step is to perform the main surgery post-delivery when the condition permits.

ORGANOPHOSPHATE INDUCED DELAYED NEUROPATHY-A CASE REPORT

Organophoshate induced delayed polyneuropathy (OPIDP) is a rare clinical condition associated with ingestion of organophosphate. Clinically the patient presents with distal lower limb weakness mainly along with paraesthesia and other symptoms of neuropathy. Nerve conduction study shows motor axonal neuropathy.Here, we are presenting a case of 23 years old INDIAN male who presented with pain and tingling sensations in lower limbs along with bilateral upper limb and lower limb paresis with difculty in getting up and walking. He had history of Dichlorvos based organophosphate ingestion around 45 days before. Electrophysiological study suggestive of Severe motor axonal polyneuropathy affecting all four limbs. No central nervous system signs were present.

A Rare Case of Extensive Spondylodiscitis

A 71-year-old man with a history of diabetes mellitus was admitted to our hospital with a 2-week history of fever and low back pain. Physical examination showed fever (38.1°C), painful palpation of the lower lumbar vertebrae and right lower limb paresis. Blood examination revealed an increased white blood cell count (16700x109/L) and C- reactive protein (22,39 mg/dL). Magnetic resonance imaging showed extensive spondylodiscitis, with osteomyelitis of the L5, S1 and S2 vertebral bodies, discitis, large epidural empyema, paraspinal and epidural abscesses. Patient was submitted to surgical treatment and was started on empirical antimicrobial therapy. Blood and intraoperative cultures were negative. Brucellosis and tuberculosis testing was negative. A 10- week course of antimicrobial therapy was performed with progressive decline of acute-phase reactants, reduction in pain and improvement of the neurological deficit. At 1-year follow up with light residual lower back pain and no neurological deficit.

A Patient with a Type I Split Cord Malformation and an Open Myelomeningocele without Advanced Lower Limb Paresis: A Case Report and a Review of the Literature

We report a rare case of a split cord malformation (SCM) combined with an open myelomeningocele (MMC) on the right hemicord. The patient was a male neonate, who exhibited an MMC in the lumbosacral region at birth. Both of his lower limbs moved with slight spasticity, but no atrophic changes or clubfoot deformities were seen. Three-dimensional computed tomography (CT) demonstrated a bony septum, and the patient was diagnosed with a type I SCM. Magnetic resonance imaging (MRI) showed an MMC on the right hemicord (a hemimyelomeningocele). The repair of the open MMC and the removal of the septum were performed immediately to prevent infection and neurological deterioration. Intraoperatively, the right hemicord was thinner than the left hemicord. No additional neurological deficits or complications appeared during treatment. Our findings suggest that when a minor hemicord is affected by both an SCM and an open MMC, good functional outcomes of the lower limbs can be achieved.

Acute transverse myelitis of childhood due to novel coronavirus disease 2019: The first pediatric case report and review of literature

The global coronavirus disease 2019 (COVID-19) pandemic appears to have some streaks of severity in pediatrics. These streaks include variable signs of respiratory distress, a new entity called multi-system inflammatory syndrome, and some evidences of neurological symptoms involving both central and peripheral nervous systems. Here, we described the first pediatric patient with COVID-19 who presented with acute transverse myelitis. An 11-year-old otherwise healthy girl presented to our clinic with acute onset of lower limbs paresis, urinary and fecal retention, alongside epigastric pain, and fever for 3 days. A neurological examination revealed a severe flaccid paraplegia in her lower limbs associated with a sensory level at T5. She was evaluated systematically for all probable causes of her symptoms, and finally, due to having a positive nasopharyngeal PCR test, she was considered to suffer from post-COVID-19 transverse myelitis. She underwent intravenous-immunoglobulin, methylprednisolone pulse, and other supportive cares without obvious results. Therefore, she underwent seven sessions of plasma exchange with little effects on muscle strength. The focal inflammation and injury of the spinal cord, otherwise known as transverse myelitis, have a wide array of potential etiologies. Transverse myelitis has been well documented to be the result of viral and bacterial infections. We believe our patient was not involved in a cytokine storm status due to good CRP, IL-6 and Ferritin levels. Albeit, we cannot certainly consider the patient to have a direct viral impactor involved in a late immunity process. To our knowledge, this is the first report of TM in the field of pediatrics occurred after COVID-19. Thus, this is critical to note that children can present with some severe types of COVID-19.

Malignant behaviour of primary intracranial Rosai Dorfman disease: A rare presentation of a benign disease

Background and purposeThe Rosai Dorfman disease (RDD) is a rare and usually benign lymphoproliferative disorder of unknown aetiology, typically characterized by head and neck lymphadenopathies. However, it may occasionally present with primary extra-nodal involvement including the central nervous system. We firstly described the potential malignant behaviour and fatal evolution of primary intracranial RDD. Illustrative caseA 69-year-old woman sought clinical attention for recurrent episodes of headache, fever and malaise associated with bilateral proptosis and left lower limb paresis. The brain MRI revealed bilateral retro-bulbar and fronto-parieto-occipital subdural lesions. The body CT did not show extracranial lesions. A right fronto-parietal craniotomy was performed and a subtotal resection was achieved. The histopathological diagnosis was consistent with RDD. Despite the patient was commenced on high-dose corticosteroids, she developed a worsening respiratory distress syndrome and a rapid systemic disease progression with liver and kidney failure. Given the poor general status, adjuvant medical and radiation therapies were not deemed safe and feasible and the patient died of multi-organ failure a month later. ConclusionsWe documented an exceptional case of primary intracranial RDD with malignant behaviour characterized by rapid systemic disease progression and poor prognosis. Although RDD with intracranial location has usually a benign and self-limiting course with good response to adjuvant treatments, it hides a malignant potential that may lead patients to death.
