Cysts In Children Research Articles

Endoscopic hybrid resection and under-water snare resection of symptomatic duodenal duplication cysts in children.

Duodenal duplication cysts are rare congenital malformations of the gastrointestinal tract, manifested in early childhood [1] [2]. They are benign lesions, although a few cases have been reported including carcinoid tumors, squamous cell carcinomas, and adenocarcinomas [3]. Endoscopic treatments include fenestration, marsupialization, snare resection, and aspiration [4] [5].

Respiratory Distress Due to Giant Pulmonary Hydatid Cyst

Pulmonary echinococcosis most frequently occurs in the right and both lower lobes. Children are more likely to develop pulmonary rather than hepatic echinococcal cysts. Some evidence suggests that echinococcal cysts develop more rapidly in the lungs of children than those of adults, which may explain the more common appearance of pulmonary cysts in children. Younger patients have larger cysts owing to their greater tissue elasticity. Large pulmonary hydatid cysts are critical because they pose a higher risk of rupture. Herein, we present an eight-year-old girl presented with severe respiratory distress due to giant hydatid cyst of right lung with shift of the mediastinum at left. The lesion displaced the trachea at left. The patient was successfully treated by parenchymal-saving operation. In conclusion, Giant hydatid lung cysts represent a distinct clinical entity most frequently encountered in children and adolescents with more serious symptoms. Although non-complicated giant hydatid cysts have a good prognosis regardless of their size and can be safely treated by parenchyma-preserving surgery.

Management of Urethral Cyst in Children

The parameatal cyst (PMC) is a benign lesion that occurs primarily in male children, generally present after birth, but may also occur in girls and adults. Although expectant management, needle puncture, decapping, and marsupialization are described as different modalities of treatment, all are associated with recurrences. We present nine pediatric cases with PMC, their clinical presentation, treatment, and outcome along with a review of the literature.

Intracranial Arachnoid Cysts in Childhood: Pathogenesis, Clinical Features, and Management

Arachnoid cysts are mostly incidental congenital lesions. Although commonly asymptomatic, it may present with nonspecific symptoms, such as headache, epilepsy, and signs of high intracranial pressure. In cases when symptoms are evident, surgical treatment has more precise indication, but the modalities and criteria for treatment remain controversial in the literature. All this makes arachnoid cysts a challenging topic in neurosurgery, raising discussions about diagnosis, management, and prognosis. This review aimed to present, in a didactic and straightforward way, already established knowledge and more recent updates, clarifying key points to guide the management and therapeutic decision of intracranial arachnoid cysts.

Why neuroendoscopy is not for all supratentorial intracranial arachnoid cysts in children: analysis of risk factors and prognosis

Cerebral neuroendoscopy is a minimally invasive approach that reduces brain exposure, retraction and mobilization of neural tissues and neurovascular structures and the treatment of intracranial arachnoid cysts by endoscopy has been widely used. Selection of the patients who are most likely to benefit remains challenging in certain cases. The purpose of this article is to raise questions and observations regarding its indication and failure in pediatric patients with suprasellar, and middle fossa arachnoid cysts. We searched English-language articles published in the last 20 years and found evidence that Neuroendoscopy emerged as an alternative to the treatment of this pathology and has its definitive role as a safe, less morbid strategy in these supratentorial pediatric arachnoid cysts and must be added to the therapeutic protocols respecting the best indication.

Abdominal wall hydatid cyst in child

The abdominal wall hydatid cyst is a rare entity. Very few cases are reported in the literature. The clinical presentation is not specific. Ultrasound can guide the diagnosis and the use of CT is often essential. We describe the case of a child who presented with a primary localization of the abdominal wall hydatid cyst, and who underwent surgical excision with good evolution.

Postoperative Complications of Microscopic Fenestration for Middle Fossa Arachnoid Cysts: A Retrospective Study of 38 Cases and Literature Review

Introduction: Middle fossa arachnoid cyst (MFAC) is one of the most common cranial cysts in children, and the various postoperative complications following cyst fenestration represent a major concern. We conducted a retrospective study in our department and performed a systematic review of the literature to identify the risk factors for complications. Methods: A retrospective survey was conducted in 38 patients with MFAC (<14 years) who underwent microscopic fenestration from January 2019 to December 2020. Postoperative complications, including postoperative hemorrhage/hematoma, subdural hygroma (SH), cranial nerve palsy, postoperative central nervous system infection, and cerebrospinal fluid (CSF) leak, were collected. A systematic PubMed search for cohort studies on surgically treated MFAC published after 1980 was performed. The postoperative complications in the included studies were illustrated. Results: The overall complication rate in our series was 7.9%, among whom, 9 patients (23.7%) developed postoperative SH, one of which required cyst-peritoneal shunting. Patients who developed SH were significantly younger (4.0 ± 1.8 vs. 6.3 ± 3.4 years, p = 0.012). Binary logistic analysis showed that a lower age could be a risk factor for developing SH (odds ratio: 0.738, p = 0.067). One patient developed a subdural hematoma. No cranial nerve palsy or CSF leak was observed. Eighteen studies were included in the systematic review, comprising 649 cases of MFAC. The most common complication was SH (4.9%), and the postoperative complication rates were similar between the microscopic and endoscopic techniques. Conclusion: The complication rate of MFAC fenestration is considerable. SH is the most common postoperative complication, and it mostly occurs in young children. Strict surgical indications should be applied for young children.

Ocular manifestations of ruptured arachnoid cysts in pediatric patients

Arachnoid cysts are intra-arachnoidal collections of cerebrospinal fluid, which can rupture spontaneously or secondary to trauma, resulting in subdural hemorrhage and increased intracranial pressure. However, there is little published data examining the ocular manifestations of ruptured arachnoid cysts. By examining the records of children treated for ruptured arachnoid cysts who also underwent an ophthalmologic examination, we sought to characterize ocular manifestations of ruptured arachnoid cysts in children.

Temporosylvian arachnoid cysts in children. Part 1: Cognitive profile of children with a temporal cyst and impact of the cyst in daily life. A prospective study in 100 consecutive children.

The aim of this study was to determine the cognitive profile of children with a temporal arachnoid cyst (TAC) and its impact on daily life. The authors prospectively analyzed the cognitive and psychological profiles of 100 consecutive children relative to age and cyst characteristics (side, cyst size, and cyst shape: convex or nonconvex) and their outcome 4 years later. Mean IQs were normal but with high heterogeneity on Full Scale IQ (FSIQ; range 59-150); 29% of children had at least one Wechsler index below the norm, in particular, Processing Speed and Working Memory Indexes. Impairments were observed in language for 31% of children, as well as in verbal memory (28%), visual memory (23%), executive function (21%), and visual attention (24%). Half of the children (50%) needed rehabilitation for learning difficulties, and 26% had academic difficulties. The parental questionnaire BRIEF (Behavior Rating Inventory of Executive Function) revealed significant executive dysfunctions in daily life for 22% of the children. One-third of the patients (34%) required psychotherapy for anxiety or social disorders, with higher rates in patients with a right-sided cyst and older children. Cyst size had very little neuropsychological impact. Convex cysts were significantly associated with worse performance than nonconvex cysts on all Wechsler indexes and FSIQ, and in language, verbal memory, attention, and visuospatial skills. Children with a convex cyst had significantly more executive and behavior difficulties in daily life and more psychotherapy than other children. The effect of cyst shape was independent of Galassi type and cyst side. Children with a ruptured cyst or an incidentally discovered cyst usually had a good cognitive level. Four years later, children without initial disorders remained stable, whereas those with difficulties who did not undergo surgery needed more rehabilitation and school adaptations. This large cohort study revealed a varied profile of children with a TAC: at initial assessment, 50% had neuropsychological difficulties and needed rehabilitation and/or psychotherapy for learning or behavior difficulties, and 50% had no difficulties, which may explain the debate about this pathology. Patients with neuropsychological difficulties had a heterogeneous profile with normal intelligence but selective cognitive and/or behavior disorders that may have a long-term impact on their quality of life, particularly those with a right-sided cyst. A neuropsychological evaluation is not always necessary for a cyst discovered incidentally, but early evaluation is essential in patients with academic, learning, or psychological disorders. When assessment shows selective disorders presumably linked to cyst location, surgery may be considered, particularly for convex cysts, as this study revealed more effects in association with cyst shape than with cyst size and significantly poorer performance with a convex cyst.

Temporosylvian arachnoid cysts in children. Part 2: Postoperative neuropsychological and clinical improvement.

The authors' objective was to study clinical, imaging, and neuropsychological changes in children who underwent surgery for a temporal arachnoid cyst (TAC). Thirty-four children were prospectively assessed similarly at diagnosis and postoperatively (mean 14 months) with clinic visits, images, cognitive tests, and parental questionnaires on mood/behavior and executive functions. The scores were compared pre- and postoperatively for the entire cohort and individually. The scores of 25 children were also compared with a control group of 23 healthy age-matched children. Parents were administered an outcome questionnaire on average 4 years postoperatively. The 34 children selected for surgery had signs of raised intracranial pressure (74%) and/or selective neuropsychological disorders presumably linked to cyst location (learning difficulties in 65%, cognitive difficulties in 56%, and mood/behavior difficulties in 47%). The majority of patients had a convex cyst (85%) and underwent microsurgical fenestration (85%). The TAC volume decreased ≥ 50% for 59% of children. On the Wechsler Intelligence Scale, the entire cohort significantly improved on Full Scale IQ and verbal and perceptual nonverbal indexes. Individually, nearly half of the children (47%) highly increased their scores (≥ 15 points) on at least one IQ index and 26% on at least two indexes. Language, working memory, episodic memory, and executive functions were also significantly improved. Improvements were more pronounced in patients with a preoperative heterogeneous profile with isolated lower scores and a left-sided cyst. Parental questionnaires showed reduction in anxiety, aggressiveness, social problems, and daily life executive disorders. Preschool-aged children improved significantly in language and verbal IQ, as did middle/high school-aged children in many domains. Individual analyses revealed improvement in 76% of cases. Cognitive scores were lower for patients preoperatively than for controls and were no longer significantly different postoperatively in verbal fluency, visual memory, and working memory. Four years later, 97% of parents described an improvement in their child, correlated with cognitive improvements. Among children with a TAC, some have no clinical signs or neuropsychological difficulties, and others may show signs of raised intracranial pressure and/or specific neuropsychological disorders that impact daily life and require significant and long-lasting rehabilitation. In these cases, consideration may be given to surgical decompression. It is interesting to note that 76% of this surgically treated cohort improved regardless of the child's age, particularly in patients with selective disorders and an impact on daily life. However, a larger number of children will need to be investigated before the true benefit of such treatment can be known.

Nasopharyngeal cysts in children

Background. Nasopharyngeal cysts are mostly congenital malformations. However, their clinical manifestation can also occur in adolescence, depending on their severity, size and location. Nasopharyngeal cysts are rare in the practice of an otolaryngologist, but can be found in nasal obstruction. The article presents the literature data on the theories of the origin, clinical manifestations, peculiarities of the diagnostics and surgical treatment of the nasopharyngeal cysts.&#x0D; Aim. To increase the efficiency of diagnostics and treatment of nasopharyngeal cysts in children on the basis of a differentiated approach to the manifestation of the disease symptoms.&#x0D; Materials and methods. 29 patients aged from 1 to 8 years (mean age 4.210.39 years) with nasopharyngeal cysts and cyst-like neoplasms were treated at the clinical sites of the Department of Otorhinolaryngology and Pediatric Department of Pirogov Russian National Research Medical University (Moscow) from 2009 to 2022.&#x0D; Results. On admission all 29 (100%) children complained of an increasing nasal obstruction, anterior and posterior purulent rhinorrhea, snoring, decreased hearing, and epiphora. 18 patients (62.1%) had a history of recurrent otitis media and were diagnosed with bilateral exudative otitis media on examination. Transnasal or transoroepipharyngeal endoscopic marsupialization and cyst coagulation with an electrosurgical complex were performed in 28 (96.5%) children. In 19 (65.5%) cases the operation was performed with a single-stage adenotomy and in 8 (27.6%) cases with tubal valvular plasty, partial destruction of the tubal tonsils.&#x0D; Conclusion. Improvement of diagnostics quality due to modern imaging technologies leads to detection of a greater number of accidental findings of nasopharyngeal cysts and requires systematization and detailed elaboration of the accumulated knowledge in the work of the pediatric otorhinolaryngologist.

Comparison of arthroscopic internal drainage and open excision for the treatment of popliteal cysts

BackgroundThe purpose of this study was to introduce the arthroscopic internal drainage with anterior-anteromedial approach for the treatment of popliteal cysts in children. To compare its clinical efficacy with open surgery.MethodsThis was a retrospective case–control study of 102 patients diagnosed with popliteal cysts from January 2018 to February 2020 who received surgery. The study included 27 cases with minimally invasive group (MI group) and 75 cases with open surgery group (OS group). The MI group included 21 males and 6 females, age 6.71 ± 2.16 years who received arthroscopic internal drainage of the cysts to adequately widen the valve opening between the cyst and the articular cavity, excised the fibrous diaphragm without complete excision of the cyst wall. The OS group included 57 males and 18 females, age 6.21 ± 1.67 years who received open excision. The clinical parameters regarding the preoperative characteristics and surgical results were compared. Ultrasound or MRI was used to identify the recurrence of the popliteal cysts. Rauschning-Lindgren grade was recorded to evaluate the clinical outcome.ResultsAll patients were followed up for at least 24 months. There were no significant differences between the two groups in age, gender, left and right sides, disease time, cyst size, length of hospitalization, preoperative Rauschning-Lindgren grade (p > 0.05). At the last follow-up, the preoperative and postoperative Rauschning-Lindgren grade was improved in both groups. Compared with the OS group, operation time was significantly shortened in the MI group (28.89 ± 4.51 min vs 52.96 ± 29.72 min, p < 0.05). The MI group was superior to the OS group in terms of blood loss and plaster fixation, with statistical significance (p < 0.05). There was obvious difference in recurrence rate between the two groups (0% vs 17.33%, p = 0.018). No postoperative complications occurred during the follow-up period.ConclusionsCompared with open excision, the treatment of popliteal cyst in children by arthroscopic internal drainage to expand the articular cavity and eliminate the “one-way valve” mechanism between the cyst and the articular cavity exhibits better clinical outcomes and significantly reduces the recurrence rate, which is worthy of further clinical promotion.

Acquired Penile Epidermoid Cysts in Children.

BackgroundIn this study, we aim to present the experience of a tertiary center regarding penile epidermoid cysts over 15 years.MethodologyPatient files of those who underwent surgical excision for penile epidermoid cysts between 2005 and 2019 were reviewed retrospectively. The demographics, clinical characteristics, etiological factors, cyst features, surgical techniques, complications, and follow-up data were analyzed.ResultsIn total, 24 penile epidermoid cysts were excised in 21 boys. The median age at the time of surgery was 52 (15-204) months. The median duration between previous surgery and cyst excision was 40 (1-180) months. In total, 11 cases had a history of circumcision, and 10 had undergone hypospadias surgery. There was no significant difference between these two etiologic groups (p > 0.05). The main symptom was an asymptomatic penile mass. The average cyst size was 9.4 ± 6.7 mm. All cysts were completely excised with incisions made over old scars, except one. No complications were observed during a median follow-up period of 50 (12-120) months, and only one recurrence was noted.ConclusionsAcquired penile epidermoid cysts may present as an early or late complication after penile surgery. Complete excision with an incision along the existing scars seems to be an effective solution for preventing new scars.

Ultrasonographic Spectrum of Cutaneous Cysts With Stratified Squamous Epithelium in Pediatric Dermatology: Pictorial Essay.

High-resolution ultrasound (HRUS) is an important diagnostic method in dermatology, especially in pediatric population. The most common type of cutaneous cysts in children corresponds to cysts with stratified squamous epithelium (CSSE). The objective is to present the different ultrasonographic appearance of histologically proven CSSE in a retrospective review. Epidermoid, milium, trichilemmal, dermoid, and pilonidal cyst and steatocystomas are included. Utility of HRUS in diagnosis of cutaneous lesions is well established. It is important to know-and stay updated-about the wide spectrum of ultrasonographic appearance of CSSE in order to avoid misleading diagnoses.

Exclusively endoscopic management of complicated pineal cysts in young children: Definitive treatment through single burr-hole technique.

Background: The management of complicated symptomatic pineal cysts in the pediatric population is challenging and variable. Surgical management may include treatment of hydrocephalus alone, or direct treatment of the cyst with or without direct hydrocephalus management. This is typically done through craniotomy-based microsurgical approaches to the pineal region or an endoscopic transventricular approach.Methods: We present a stepwise minimally invasive technique to treat complicated pineal cysts in young children associated with an obstructive hydrocephalus in a single procedure through third ventriculostomy combined with an intraventricular marsupialization of the pineal cyst through a single burr-hole using stereotactic navigation.Results: Two young patients with over 2 years of follow-up have done well without complication using this technique. Other literature reports for complex pineal cysts in pediatric patients are reviewed and this technique is not previously described for this population.Conclusion: Endoscopic third ventriculostomy and cyst marsupialization using a single burr-hole and stereotactic navigation for symptomatic or enlarging pineal cysts in children allow for minimally invasive management, a rapid recovery, short hospital stay, and durable outcome owed to redundant CSF flow pathways.

Evaluation of preoperative cutaneous fistula as a risk factor for recurrence of thyroglossal duct cyst in children.

A preoperative cutaneous fistula was a critical and independent risk factor for recurrence of operated TGDC, whereas age and TGDC infection were not identified as risk factors for recurrence after surgery. This information should be given to patients and parents before surgery. • The risk factors for recurrence after thyroglossal duct cyst surgery described in the literature are preoperative infection and young age, but this is not supported by strong evidence. • The role of cutaneous fistula formation is unclear. •The main risk factor for recurrence of TGDC is the presence of a preoperative cutaneous fistula, with an estimated hazard ratio of 4.95 (p = 0.016) in multivariate analysis. • The presence of two preoperative infections was also associated with a greater risk of recurrence in univariate analysis; age and gender were not associated with an increased risk of recurrence.

Clinical variety and prognosis of intracranial arachnoid cysts in children.

Arachnoid cysts (AC) occur in different intracranial locations. Management and prognosis depend on the clinical presentation and treatment guidelines do not exist. With this study, we want to demonstrate the clinical variety of arachnoid cysts in children and place a focus on outcome factors in operated cases. This retrospective study of a consecutive single unit series of children, who underwent AC surgery between January 2010 and September 2019, provides demographic, clinical, imaging data, and information about surgical treatment and outcome. Overall, 63 patients (71.4 male) underwent surgery. Mean age was 50months (0-191). Mean follow-up was 40months (0-121). Eighty-one percent of patients presented with symptoms/signs of raised ICP. Focal neurological deficits were present in 15.9%, headache in 11.1% of children. Galassi cysts represented the predominant type (30.2%), followed by suprasellar (14.3%), quadrigeminal (12.7%), retrocerebellar, CPA and midline (each 11.1%), and hemispheric cysts (7.9%). Endoscopic and microsurgical fenestrations were performed in 27% and 58.7%, stent or shunt insertion in 6.3%/57.9% of the cases. In 33.3% of the cases one and in 12.7%, a second reintervention became necessary. Reoperation rate was significantly higher in children < 1year (p = 0.003). Cyst volume decreased in 85.7%. Seventy percent of the patients were symptom free, 5% suffered from headache, and 22% from developmental disorders. All focal neurological symptoms resolved. Complication rate and outcome are depending on age and cyst location. Recurrence and revision rates are significantly higher in young infants (p = 0.003). Midline cysts with CCA are associated with developmental disorders.

How we acquire suturing skills for laparoscopic hepaticojejunostomy

Laparoscopic choledochal cyst excision and hepaticojejunostomy is a representative surgical procedure requiring laparoscopic suturing including needle driving and knot tying. Laparoscopic needle driving and knot tying is a highly technically demanding skill, especially in small infants and children. We developed a laparoscopic hepaticojejunostomy simulator for training. This simulator was developed for a 1-year-old infant body size based on computed tomography data and reproduced a pneumoperitoneum condition based on 3D scanner data of the clinical situation. Surgeon in training (SITs) of our institution have to acquire practice of laparoscopic hepaticojejunostomy using a simulator before performing clinical cases. Thirteen cases of choledochal cyst have been managed at our institution since the introduction of practice using this simulator in 2016. Six SITs performed 13 cases of laparoscopic choledochal cyst excision and hepaticojejunostomy. There were no cases of anastomotic bile leakage. Laparoscopic disease-specific simulator practice is effective for the acquisition of secure hepaticojejunostomy skills for the treatment of choledochal cysts in children as off-the-job training.
