Brain abscess following solid organ transplantation: A 21-year retrospective study.

Development of brain abscess following solid organ transplantation is associated with significant morbidity and mortality. We undertook a descriptive study to evaluate the etiology, clinical manifestations, diagnosis, management, and outcomes of brain abscess in solid organ transplant (SOT) recipients at three major transplant centers in the United States. This is a retrospective study of adults with brain abscess following SOT between January 2000 and June 2021 at Mayo Clinic sites in Arizona, Minnesota, and Florida. A total of 39 patients were diagnosed with a brain abscess following SOT. The most common pathogens were Nocardia sp. (24 cases, 61.5% [Nocardia farcinica, 37.5%]), followed by fungi (12 cases, 30.7% [Aspergillus sp., 83.3%]). The majority were kidney transplant recipients (59%). Median time to brain abscess diagnosis was 1.3 years (range, 29 days-12 years) after SOT; 10 of 12 patients (83%) with fungal brain abscess were diagnosed within 1 year after SOT. Twelve patients underwent brain biopsy for diagnosis (25% Nocardia vs. 50% fungal), eight (20.5%) underwent surgical resection of the abscess, and 31 (79.5%) received antimicrobial therapy alone. Median time to brain abscess resolution was 166 days for Nocardia and 356 days for fungal pathogens. Eleven of 39 patients (28.2%) died as a result of their brain abscess, including four of 24 patients (16%) with Nocardia and six of 10 patients (60%) with Aspergillus brain abscess. All-cause mortality was 43.6%. Brain abscess remains an uncommon infectious complication following SOT. Nocardia and fungi accounted for 92% of pathogens in our cohort. Fungal brain abscess portends a poor prognosis.

Cause of Death for Heart Transplant Patients, an Autopsy Study

IntroductionHeart transplantations are lifesaving for patients with end-stage heart failure. It is pertinent for the multi-disciplinary care team to understand how heart transplant patients succumbed to death and the complications that occurred. In this study, we performed a comprehensive retrospective review of all the autopsies performed in our institute for heart transplant patients and report the trend of demographic data, cause of death, and autopsy findings. Materials and MethodsReports, photos, and slides of autopsies performed at our institute from 1990-2023 for heart transplant patients were reviewed. Pertinent demographic data (age, gender, pre-transplant diagnosis), clinical data (clinical history of rejection, complication, time interval from transplant to death, clinical cause of death) and pathological findings (allograft pathology, infectious etiology, other findings related to cause of death) were reviewed, documented, and analyzed. ResultsWe identified 88 cases, consisting of 53 male and 35 female patients. The median age at transplant was 26 years, while 28.5 years was the median age at death. The median interval from transplant to death was 10 months. The cases were classified in three categories based on length of survival post-transplant: Superacute (<1 month, 21%), Early (1 month-12 months, 30%), and Late (>12 months, 49%). Slides were unavailable for review in 15 cases, which were excluded from cause of death (COD) evaluation. We categorized 41.1% of cases as allograft-related COD and 58.9% as non-allograft-related COD. Six of the CODs were not perceived premortem. These unexpected CODs included moderate/severe acute cellular rejection in a patient with a recently negative biopsy, dehiscent suture caused by a fungal abscess, an aorto-bronchial fistula, CMV myocarditis, acute abdominal bleeding, and ruptured atherosclerotic plaques with acute myocardial infarction. ConclusionWe systematically reviewed thirty-three years of heart transplant autopsies. We found that 41.1% of deaths were allograft related, with infection being the most frequent COD. While the rate of unexpected findings was low, the findings demonstrate the continued utility of autopsy in patient evaluation.

Fungal Spinal Epidural Abscess: A Mystifying Quagmire

Fungal Spinal Epidural Abscess: A Mystifying Quagmire

COVID-19-Associated Rhino-Orbito-Cerebral Mucormycosis: A Single Tertiary Care Center Experience of Imaging Findings With a Special Focus on Intracranial Manifestations and Pathways of Intracranial Spread.

Background and objective The COVID-19pandemic and mucormycosis epidemic in India made research on the radiological findings of COVID-19-associated mucormycosis imperative. This study aims todescribe the imaging findings in COVID-19-associated mucormycosis, with a special focus on the intracranial manifestations. Methodology Magnetic resonance imaging (MRI) scans of all patients with laboratory-proven mucormycosis and post-COVID-19 status, for two months, at an Indian Tertiary Care Referral Centre, were retrospectively reviewed, and descriptive statistical analysis was carried out. Results A total of 58 patients (47 men, 81%, and 11 women, 19%) were evaluated. Deranged blood glucose levels were observed in 47 (81%) cases. The intracranial invasion was detected in 31 (53.4%) patients. The most common finding in cases with intracranial invasion was pachymeningeal enhancement (28/31, 90.3%). This was followed by infarcts (17/31, 55%), cavernous sinus thrombosis (11/58, 18.9%), fungal abscesses (11/31, 35.4%), and intracranial hemorrhage (5/31, 16.1% cases). The perineural spread was observed in 21.6% (11/51) cases. Orbital findings included extraconal fat and muscle involvement, intraconal involvement, orbital apicitis, optic neuritis, panophthalmitis, and orbital abscess formation in decreasing order of frequency. Cohen's kappa coefficient of interrater reliability for optic nerve involvement and cavernous sinus thrombosis was 0.7. Cohen's coefficient for all other findings was 0.8-0.9. Conclusions COVID-19-associated rhino-orbito-cerebral mucormycosis has a plethora of orbital and intracranial manifestations. MRI, with its superior soft-tissue resolution and high interrater reliability, as elucidated in this study, is the imaging modality of choice for expediting the initial diagnosis, accurately mapping out disease extent, and promptly identifying and scrupulously managing its complications.

Imaging in a rare case of cerebral phaeohyphomycosis caused by Cladophialophora bantiana in a renal transplant patient: a case report and the literature review

BackgroundCerebral phaeohyphomycosis is a rare and potentially life-threatening fungal infection caused by dematiaceous fungi (Levin TP et al. in J Clin Microbiol 42(9):4374–4378, 2004). It may occur in both immunocompetent and immunodeficient individuals, with a relatively higher incidence in the former (Revankar SG et al. in J Trop Med Hyg 38(1):206–222, 2004). A search of the Pubmed and Google Scholar databases revealed seven cases of cerebral phaeohyphomycosis in renal transplant patients caused by Cladophialophora bantiana (C. bantiana).Case presentationA 35-year-old male patient who had undergone a renal transplant presented with fever, imbalance while walking, and focal seizures involving the right lower limb. Magnetic Resonance Imaging (MRI) of the brain showed two lesions in the cerebral hemispheres. Craniotomy with excision of the lesion was done. The Periodic Acid Schiff (PAS) stain and the tissue culture on the Sabouraud dextrose agar suggested C. bantiana. The broad-spectrum antifungal drugs were started. However, the patient deteriorated in the subsequent follow-ups and eventually died of the disease.ConclusionsWe present a detailed report on the imaging characteristics of a rare fungal brain abscess caused by C. bantiana, which is the first case of its kind (refer to Table 1). In immunodeficient cases, intracranial pathologies can encompass a wide range of conditions, from infections to neoplasms, which often exhibit significant imaging overlap. In such a setting, the remote possibility of phaeohyphomycosis is easy to miss clinically and imaging-wise. MRI can narrow down the differential diagnosis and raise suspicion. In every suspicious case, it is of the utmost importance to correlate with the histopathology and the culture reports to initiate the prompt targeted therapy and avoid a fatal outcome. Complete excision of the abscess and antifungal agents like Voriconazole and Posaconazole are the mainstay of management in these patients.

The Effect of Contrast-enhanced Ultrasound via Vessels and Surgical Drains Guidance Percutaneous Catheter Drainage in the Treatment of Pyogenic Liver Abscess.

Pyogenic liver abscess (PLA) is a purulent disease caused by microbial contamination of liver parenchyma and includes amoebic liver abscess, fungal liver abscess, and the most common bacterial liver abscess. Explore the efficacy of contrast-enhanced ultrasound (CEUS) via vessels and surgical drain guidance percutaneous catheter drainage (PCD) in the treatment of pyogenic liver abscesses (PLA). A total of 86 PLA patients who underwent PCD treatment in our hospital from May 2018 to February 2023 were retrospectively selected. Of them, 41 patients were treated under intravenous CEUS guidance (Control group), and 45 patients were treated under CEUS via vessels and surgical drain guidance (study group). Perioperative characteristics, treatment effectiveness, and incidence of complications were analyzed and compared between groups. The duration of surgery, drainage, white blood cell recovery, body temperature recovery, and hospitalization in the study group were longer than those in the control group (P<0.05). The total effective rate of the study group (95.56%) was higher than that of the control group (80.49%) (P<0.05). The incidence of complications in the study group (4.44%) was lower than that in the control group (19.51%) (P<0.05). Compared with intravenous CEUS alone, treatment under CEUS via vessels and surgical drains-guided PCD was associated with shorter surgical time, faster recovery, better treatment effect, lower risk of complications, and ensured treatment safety in PLA patients.

Mortality associated with SARS-CoV-2 in nondomestic felids.

Between September and November 2021, 5 snow leopards (Panthera uncia) and 1 lion (Panthera leo) were naturally infected with severe acute respiratory coronavirus 2 (SARS-CoV-2) and developed progressive respiratory disease that resulted in death. Severe acute respiratory syndrome coronavirus 2 sequencing identified the delta variant in all cases sequenced, which was the predominant human variant at that time. The time between initial clinical signs and death ranged from 3 to 45 days. Gross lesions in all 6 cats included nasal turbinate hyperemia with purulent discharge and marked pulmonary edema. Ulcerative tracheitis and bronchitis were noted in 4 cases. Histologically, there was necrotizing and ulcerative rhinotracheitis and bronchitis with fibrinocellular exudates and fibrinosuppurative to pyogranulomatous bronchopneumonia. The 4 cats that survived longer than 8 days had fungal abscesses. Concurrent bacteria were noted in 4 cases, including those with more acute disease courses. Severe acute respiratory syndrome coronavirus 2 was detected by in situ hybridization using probes against SARS-CoV-2 spike and nucleocapsid genes and by immunohistochemistry. Viral nucleic acid and protein were variably localized to mucosal and glandular epithelial cells, pneumocytes, macrophages, and fibrinocellular debris. Based on established criteria, SARS-CoV-2 was considered a contributing cause of death in all 6 cats. While mild clinical infections are more common, these findings suggest that some SARS-CoV-2 variants may cause more severe disease and that snow leopards may be more severely affected than other felids.

Pathobiology of Candida auris infection analyzed by multiplexed imaging and single cell analysis.

Fungal organisms contribute to significant human morbidity and mortality and Candida auris (C. auris) infections are of utmost concern due to multi-drug resistant strains and persistence in critical care and hospital settings. Pathogenesis and pathology of C. auris is still poorly understood and in this study, we demonstrate how the use of multiplex immunofluorescent imaging (MxIF) and single-cell analysis can contribute to a deeper understanding of fungal infections within organs. We used two different neutrophil depletion murine models (treated with either 1A8-an anti-Ly6G antibody, or RB6-8C5-an anti-Ly6G/Ly6C antibody; both 1A8 and RB6-8C5 antibodies have been shown to deplete neutrophils) and compared to wildtype, non-neutropenic mice. Following pathologist assessment, fixed samples underwent MxIF imaging using a C. albicans antibody (shown to be cross-reactive to C. auris) and immune cell biomarkers-CD3 (T cells), CD68 (macrophages), B220 (B cells), CD45 (monocytes), and Ly6G (neutrophils) to quantify organ specific immune niches. MxIF analysis highlighted the heterogenous distribution of C. auris infection within heart, kidney, and brain 7 days post-infection. Size and number of fungal abscesses was greatest in the heart and lowest in brain. Infected mice had an increased count of CD3+, CD68+, B220+, and CD45+ immune cells, concentrated around C. auris abscesses. CD68+ cells were predominant in wildtype (non-neutropenic mice) and CD3+/CD45+ cells were predominant in neutropenic mice, with B cells being the least abundant. These findings suggest a Th2 driven immune response in neutropenic C. auris infection mice models. This study demonstrates the value of MxIF to broaden understanding of C. auris pathobiology, and mechanistic understanding of fungal infections.

Evolution of neuroimaging findings in angioinvasive cerebral aspergillosis in a pediatric patient with leukemia during long-term observation

The central nervous system is one of the most common sites of aspergillosis involvement in immunocompromised people, just after sinopulmonary infections. Neuroimaging modalities are crucial for the diagnosis of cerebral aspergillosis (CA). Here, we describe a rare case of concurrent mixed aspergillosis infection with Aspergillus fumigatus and Aspergillus niger in a 2-year-old leukemic boy. The first neuroimaging finding, which was followed by focal seizures, was recognized as extensive cerebral hemorrhage in the absence of thrombocytopenia and coagulopathy. As the patient survived for more than 4 months after diagnosis, we were able to perform a neuroimaging evaluation during long-term observation. In serial neuroimaging studies, a secondary fungal abscess was observed at the site of hemorrhagic infarctions. Finally, the patient died from bacterial sepsis. In this case study, we try to categorize the neuroimaging findings of CA into distinct phases to better understand how CA changes over time.

Invasive Fungal Infection Mimicking Infarctions in a Child with Acute Lymphoblastic Leukemia

Invasive fungal infection is a major cause of morbidity and mortality after intensive chemotherapy in patients with leukemia who present with febrile neutropenia. The most common sites of involvement are the lungs, sinonasal region, and disseminated blood stream infection. Visceral organ involvement is usually seen in the form of fungal abscesses, with parenchymal infarcts being less common. We report an unusual case of invasive fungal infection presenting with extensive liver infarction, global renal infarction, and multiple brain lesions in a 4-year-old boy with acute lymphoblastic leukemia on induction chemotherapy.

Fungal abscess of the parotid gland - the value of microbiological assessment.

Fungal parotitis is rare and the sequela parotid abscess exceedingly so. We report our experience with Candida glabrata and Candida albicans parotid gland abscesses in critically ill HIV-positive patients and highlight the value of microbiological assessment to tailor management.

Acrophialophora: A Comprehensive Review of Clinical Guidelines and Diagnosis.

Acrophialophora is a saprotrophic genus of fungi found in both temperate and tropical regions. The genus is comprised of 16 species, with the subspecies A. fusispora and A. levisnecessitating the most clinical concern. Acrophialophora is an opportunistic pathogen with a broad range of clinical manifestations; the fungushas been implicated in cases of fungal keratitis, lung infection, and brain abscess. Acrophialophora infection is particularly of concern for immunocompromised patients, who often present with a more severe disease course involving disseminated infection and may not exhibit typical symptoms. Early diagnosis and therapeutic intervention are critical to the successful clinical management of Acrophialophora infection. Guidelines for antifungal treatment have yet to be established, partially due to the lack of documented cases. Aggressive use of antifungal agents and long-term treatment is required, especially in immunocompromised patients and patients with systemic involvement, due to the potential for morbidity and mortality. In addition to outlining the rarity and epidemiology of the disease, this review provides an overview of the diagnosis and clinical management ofAcrophialophorainfection to facilitate an early diagnosis and appropriate interventions.

Imaging Features of COVID-19-Associated Acute Invasive Fungal Rhinosinusitis

Abstract Background Acute invasive fungal rhinosinusitis (AIFR) is a rare, rapidly progressive, and life-threatening infection involving the nasal cavity and paranasal sinuses. Purpose of this study is to describe imaging features of coronavirus disease-2019 (COVID-19)-associated AIFR. Methods This was a retrospective observational study. Inclusion criteria: (1) post-COVID-19 patients with fungal rhinosinusitis detected on potassium hydroxide smear or histopathology; (2) onset of symptoms (facial pain, dental pain, facial swelling or discoloration, nasal bleed, periorbital swelling, ptosis, redness of eyes, vision loss) less than 4 weeks; and (3) magnetic resonance imaging/computed tomography (MRI/CT) done within 5 days before surgery. Exclusion criteria: (1) cases of sinusitis without a history of previous COVID-19 infection; and (2) cases in whom fungal hyphae were not demonstrated on pathological examination. Noncontrast CT and dedicated MRI sequences were done initially. Site of involvement, unilateral/bilateral involvement, pattern of mucosal thickening, enhancement pattern, periantral invasion, orbital invasion, intracranial involvement, perineural spread, vascular involvement, and bony involvement were recorded. CT and MRI imaging features were compared. Results Analysis of 90 studies (CT and MRI) in 60 patients was done. Most common site of involvement was ethmoid followed by maxillary sinus. Bilateral disease was more common. Mucosal thickening with T2 hypointense septations was seen in 88.4% MRI studies. Periantral and orbital involvement was seen, respectively, in 84.6% and 55.7% cases of MRI. Intracranial involvement was noted in form of meningitis, cerebritis, abscess, infarct, hemorrhage, cavernous sinus, or perineural invasion. Vascular involvement was noted in form of vascular occlusion (n = 3), vascular narrowing (n = 3), and pseudoaneurysm (n = 2). MRI was more sensitive in detecting periantral invasion, deep infratemporal fossa, cavernous sinus involvement, perineural invasion, optic nerve involvement, and vascular occlusion and narrowing, while CT was superior in identification of bony erosions. Conclusion Early recognition of AIFR in post-COVID-19 patients is important to prevent disease-related morbidity/mortality. Several rarely described findings are noted in our series of AIFR, like optic nerve involvement, pituitary fungal abscess, perineural spread, fungal aneurysms, and arteritis-related posterior circulation infarcts. MRI is superior for early detection of disease and in estimation of extent of disease, compared with CT. Imaging can help in early detection of AIFR, which has a significant impact on patient outcome.

A rare case of acquired A haemophilia associated with bullous pemphigoid complicated by cerebral fungal abscesses and multiple opportunistic infections

Acquired A Haemophilia (AHA) is a rare autoimmune disease caused by production of anti VIII factors antibodies that could cause multiple haemorrhagic manifestations. Usually idiopathic, could be related with other conditions, such as Bullous Pemphigoid (BP), an autoimmune dermatologic disease.

Fungal brain abscesses caused by Acremonium species

Unusual fungal agents that exist environmentally as saprophytes can often lead to opportunistic infections, hyalohyphomycosis is a group of fungal infections caused by fungi characterized by hyaline septate hyphae and can infect both immunocompetent as well as immunocompromised patients, and Acremonium has drawn the attention of clinicians and microbiologists, as a potential pathogen in patients with and without underlying risk factors. It has also been increasingly implicated in systemic fungal diseases. Herein, we describe a case presentation of an immunocompromised patient with fungal brain abscesses due to Acremonium species.

Ataxia and muscle weakness after thiopental anaesthesia in a horse being treated with fluconazole

AbstractAn 8‐year‐old, male, neutered Argentinian polo pony underwent two ocular surgeries due to a fungal abscess. The horse was on treatment with fluconazole before and during the time when the two anaesthetic procedures took place. The only difference between anaesthetic events was the induction agent. During the first anaesthetic procedure, ketamine was used. However, during the second anaesthetic procedure, due to ocular fragility sodium thiopental was preferred to avoid increase in intraocular pressure. The first anaesthetic duration was 130 minutes, and standing was achieved after 20 minutes of isoflurane discontinuation, with no complications. The second anaesthetic procedure lasted for 60 minutes, but standing was not achieved until 70 minutes after isoflurane discontinuation. The horse was ataxic with muscle weakness for 6 hours after standing. However, the horse recovered successfully and was discharged 2 months after the first surgical procedure.

Risk Factors, Diagnosis, and Treatment of Neonatal Fungal Liver Abscess: A Systematic Review of the Literature.

(1) Background: Although invasive fungal infections are a major cause of neonatal morbidity and mortality, data on the incidence and outcomes of localized abscesses in solid organs due to fungal infections are scarce. The aim of this study was to consolidate evidence and enhance our understanding on neonatal liver abscesses due to invasive fungal infections. (2) Methods: An electronic search of the PubMed and Scopus databases was conducted, considering studies that evaluated fungal liver abscesses in the neonatal population. Data on the epidemiology, clinical course, treatment, and outcome of these infections were integrated in our study. (3) Results: Overall, 10 studies were included presenting data on 19 cases of neonatal fungal liver abscesses. Candida spp. were the most common causative pathogens (94.7%). Premature neonates constituted the majority of cases (93%), while umbilical venous catheter placement, broad spectrum antibiotics, and prolonged parenteral nutrition administration were identified as other common predisposing factors. Diagnosis was established primarily by abdominal ultrasonography. Medical therapy with antifungal agents was the mainstay of treatment, with Amphotericin B being the most common agent (47%). Abscess drainage was required in four cases (21%). Eradication of the infection was achieved in the majority of cases (80%). (4) Conclusions: Even though fungal liver abscess is a rare entity in the neonatal population, clinicians should keep it in mind in small, premature infants who fail to respond to conventional treatment for sepsis, particularly if an indwelling catheter is in situ. A high index of suspicion is necessary in order to achieve a timely diagnosis and the initiation of the appropriate treatment.

Comparison of MRI Findings in Diabetic and Nondiabetic Patients with Rhino-Orbito-Cerebral Mucormycosis

Objective Rhino-orbito-cerebral mucormycosis (ROCM) has emerged as a key concern during the period of coronavirus disease 2019 (COVID-19) pandemic. Diabetes mellitus is a known risk factor for invasive fungal infection. The aim of this article was to study and compare the radiological features of COVID-19-associated ROCM between diabetic and nondiabetic patients using magnetic resonance imaging. Materials and Methods A retrospective observational study comprising 78 diabetics and 40 nondiabetics who developed ROCM after COVID-19 was conducted. The imaging data of both groups were analyzed, findings tabulated and compared using statistical methods. Results Maxillary and ethmoid sinuses were commonly involved in both groups. Periantral fat and orbits were the most common sites of disease extension. The spread of infection to periantral soft tissue was significantly higher in diabetics (p = 0.049). Diabetics were more likely to have bone, orbit, and brain involvement than nondiabetics, although the difference was not statistically significant. Diabetic patients were the only ones to experience complications such as fungal abscess and cavernous sinus and internal carotid artery involvement. However, a considerable number of nondiabetic patients (22.5%) also had an intracranial extension of disease. Conclusion The radiological appearances and common sites of invasion in ROCM are similar in diabetic and nondiabetic patients. The extensive spread of infection to extra-sinus regions can occur in nondiabetic patients with COVID-19 but is less frequent compared with diabetics.

P272 Fungal brain abscess in the era of COVID 19: an experience from a tertiary care Neurosciences Institute in South India

Poster session 2, September 22, 2022, 12:30 PM - 1:30 PMIntroductionSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is ruling the world for more than 2 years since 2020. In 2021, the second wave of COVID-19 attributed to the ‘delta variant’ swept across India, causing significant morbidity and mortality. In addition, the epidemic of COVID-19-associated mucormycosis affected the Indian subcontinent specifically, with a whopping 41 512 cases and 3554 deaths attributed to this dreadful disease.MethodsThe single-center retrospective cross-sectional study was aimed to determine the impact of COVID-19 on fungal brain abscess cases at a non-COVID tertiary care Neurosciences Institute in South India. The study included all cases diagnosed with fungal brain abscess microbiologically (microscopy and/or fungal culture), supported by radiological findings or by histopathological examination. Cases of brain abscess which were negative for fungal elements by microscopy, culture, and imaging were excluded from the study. Fungal culture was done on routine mycological media as per standard procedures. Fungal identification was done by microscopic morphology, MALDI-TOF MS, and ITS sequencing.ResultsA total of 406 cases of brain abscess were recorded between January 2020 and April 2022. Out of these, 26 (6.4%) were cases of fungal brain abscess. In 2020, three out of 153 (2%) cases had a fungal etiology, while it was 10.4% (22/211) in 2021 and 0.24% (1/42) till April 2022. Overall, a male preponderance was observed (20/26, 77% were males). The cases had an even distribution from 6 to 62 years, with no predilection in any particular age group. The most common underlying comorbidity was type 2 diabetes mellitus (13/26, 50%). Four cases had a past history of COVID-19. Radiological suspicion of fungal infection was present in all the cases. Mycological examination (wet mount and 20% KOH mount) of brain abscess pus from all the cases revealed fungal elements. Out of 26 cases, 23 cases showed hyaline, broad aseptate hyphae, 2 showed melanized septate hyphae and 1 showed budding yeast cells with pseudohyphae and arthroconidia on direct microscopy. Culture positivity was observed in 15 cases (57.7%). Out of 23 suspected cases of rhinocerebral mucormycosis based on clinical, radiological, and direct microscopic findings, fungal culture was positive in 13 cases, all of which were identified as Rhizopus arrhizus. Out of two cases that showed melanized hyphae in direct microscopy, one grew a dematiaceous mold that was identified as Cladophialophora bantiana. The other melanized fungus failed to grow in culture. The single case of brain abscess caused by a yeast-like fungus was attributed to Trichosporon dohaense, identified by ITS sequencing. It was initially misidentified as T. ovoides/T. mucoides by VITEK MS due to lack of mass spectral database for T. dohaense.ConclusionsA significant increase in the incidence of fungal brain abscess has been observed in the COVID-19 era, particularly with each new wave of infection. Clinical features along with imaging and mycological findings are crucial in making an early diagnosis and decision regarding antifungal therapy. Accurate identification to the species level is necessary to guide optimal antifungal therapy as several species exhibit emerging resistance to antifungal drugs.
