RESUMO

Fonsecaea monophora is a species of Fonsecaea that belongs to Chaetothyriales. It is usually isolated from tropical and subtropical regions, causing reactive inflammation, skin abscesses, and pain. Cerebral infection caused by F. monophora is rare but often fatal. Diagnosing this disease at an early stage is difficult, and appropriate antifungal therapy is often delayed as a result. We report the case of a 53-year-old woman with type 2 diabetes who presented with a headache 2 months ago and progressive right-sided weakness of 1 month's duration. Magnetic resonance imaging revealed a space-occupying lesion in the left frontal lobe and corpus callosum. The cystic mass was removed by surgical intervention, and the identification of the sample based on sequencing of the internal transcribed spaced region in BLAST-N search showed that the sequences producing most significant alignments were F. monophora or similar (query cover 99%, E value 0.0, per ident 99.84). The patient was treated with a 3-month course of twice daily voriconazole, leading to complete recovery.

RESUMO

PURPOSE: Cladophialophora bantiana is a wonted melanized fungus causing brain abscess. In past many cases were reported from Asia, particularly from India. Of late, there is a rise in cases in places besides Asia and hence a review of the cases is warranted. METHODS: We present a case of fatal cerebral phaeohyphomycosis caused by C. bantiana and conduct a systematic review of culture confirmed brain abscess due to C. bantiana reported between 2015 and 2022. RESULTS: Of the 39 cases found, majority (68%) were immunocompromised. The various clinical presentations were headache (53%), hemiparesis (34%), visual disturbance (25%), altered sensorium (18%), aphasia/dysarthria (12%) and seizures (9%). Isolated lesion was observed in 18 (60%) patients. In the sequence of occurrence, the lesions were in frontal (30%), temporal (27%) and parietal (20%) region. There were five cases with coinfections such as concurrent detection of Nocardia pneumonia in two cases, toxoplasma DNA in brain abscess, coexisting pulmonary Cryptococcus neoformans infection and coexisting Candida in a case of brain abscess in one case each. Surgical intervention was performed in 84% cases. Antifungal therapy included voriconazole (80%), liposomal amphotericin B (76%), 5-fluorocytosine (30%), posaconazole (10%), and amphotericin B deoxycholate (6%). The overall mortality was 50% with lower mortality (42%) in regions outside Asia compared to Asia (63.6%) though not statistically significant. CONCLUSIONS: C. bantiana brain abscess is an emerging infection worldwide. Next generation sequencing is an upcoming promising diagnostic test. Early complete excision of the lesion with effective antifungals may improve the outcome.

RESUMO

INTRODUCTION: Cladophialophora bantiana is a filamentous fungus, known as a dematiaceous fungus because of the presence of melanin. This fungus is of clinical importance because it is neurotropic and causes cerebral phaeohyphomycosis. MATERIAL AND METHODS: The available scientific information on the development of cerebral phaeohyphomycosis caused by Cladophialophora bantiana was analysed by selecting articles from the PubMed, Scopus and Google Scholar databases that describe case reports of fungal infection by C. bantiana in adults, taking into account the analysis of the patients' symptomatology, clinical history and neuroanatomical damage, in addition to considering the mortality of the condition. RESULTS: India and United States were the countries with most case reports, with 32 and 11 cases respectively. Moreover, in terms of neuroanatomical lesions, the majority of patients suffered mixed lesions (29%) and frontal lobe lesions (22%). In accordance with the patients' condition, the pathology has a mortality rate of 62%. CONCLUSIONS: It is concluded that cerebral phaeohyphomycosis has a high mortality rate, there is no standardised treatment and, in most cases, the fungal infection of the brain is mixed and affects several different parts of it. Furthermore, if not diagnosed and treated in time, it can lead to the patients' death.

RESUMO

Central nervous system (CNS) phaeohyphomycosis is a rare and often fatal fungal infection. Our study reported a case series of eight CNS phaeohyphomycosis cases at our institution over the past 20 years. We did not observe the common pattern of risk factors, abscess location, or number of abscesses among them. Most patients were immunocompetent without classic risk factors for fungal infection. Early diagnosis and aggressive management with surgical intervention and prolonged antifungal therapy can lead to a favorable outcome. The study highlights the need for further research to better understand the pathogenesis and optimal management of this challenging rare infection.

RESUMO

A right-handed man in his early 60s with hypertension controlled by a single prescription medication presented with left-sided heaviness and intermittent right occipital headache. Initial diagnostic workup was unremarkable. CT revealed an enhancing lesion located in the right parietal lobe, with mild mass effect on the right occipital horn, indicative of a brain abscess. The patient was initially treated with a course of empirical antibiotics, including ceftriaxone, vancomycin, metronidazole and dexamethasone. The neurosurgery team aspirated the abscess the following day and extracted yellow pus that was sampled for bacterial and fungal cultures. These cultures returned positive for Rhinocladiella mackenziei, prompting a discontinuation of the empirical antibiotics and initiation of intravenous liposomal amphotericin B for 4 weeks. Intravenous posaconazole was added to the patient's existing therapy regimen, which was substituted with oral isavuconazole on discharge. The patient continues to take isavuconazole, and follow-up imaging has demonstrated regression of the abscess.

RESUMO

OBJECTIVES: To report cases of cerebral phaeohyphomycosis at a tertiary hospital in Riyadh, Saudi Arabia. Phaeohyphomycetes are a widely distributed group of fungi whose cell walls contain 1,8 dihydroxynaphthalene-melanin. Cerebral infections caused by these fungi are uncommon and primarily associated with neurotrophic phaeohyphomycetes. METHODS: In January of 2020 we looked back to identify cases of culture-positive cerebral phaeohyphomycosis from our medical records at King Faisal Specialist Hospital and Research Center in Riyadh, Saudi Arabia. Data on demographics, potential risk factors, clinical presentation, treatment, and outcomes were analyzed. RESULTS: Twelve cases of cerebral phaeohyphomycosis were identified, of which 4 were caused by Rhinocladiella mackenziei and the other 8 were caused by various phaeohyphomycetes. There were 2 cases caused by Neoscytalidium dimidiatum, and one case each caused by the following: Acrophialophora fusispora, Chaetomium atrobrunneum, Exophiala dermatitidis, Exerohilum rostratum, Fonsecaea pedrosoi, and Cladophialophora bantiana. Most patients (10 of 12) had underlying immunosuppression. R. mackenziei caused a brain-only infection manifesting as abscess formation. Four patients survived for more than a year after therapy. Surgical evacuation and triazole therapy with posaconazole or itraconazole, alone or in combination with other antifungal agents, were associated with success. CONCLUSION: Cerebral phaeohyphomycosis is an uncommon fungal infection that primarily affects immunocompromised patients and is associated with poor prognosis. R. mackenziei is the most prevalent fungus in our facility and has been linked to a universal mortality.

RESUMO

Background: Neoscytalidiumdimidiatum is an opportunistic dematiaceous fungus belonging to the class Dothideomycetes.Case reportWe report a case of N. dimidiatum cerebral phaeohyphomycosis post COVID-19 infection in a 32-year-old male from Iran. The causative agent was identified by cytopathology, routine mycological methods, and DNA sequencing of the internal transcribed spacer (ITS) region of rDNA. Apart from COVID-19 complications and the corticosteroid therapy, no underlying condition was diagnosed. The symptoms suggesting the fungal infection were shown two weeks after being discharged from COVID-19 hospital stay. Magnetic resonance of the brain showed a multi-focal central nervous system infection. The delayed identification of the fungus and, thus, a late starting of the antifungal treatment with amphotericin B, might have affected the patient outcome as he finally died.ConclusionsConsidering the rare incidence of N. dimidiatum infections, this case should aware us about them, leading to a timely antifungal management.

Antecedentes: Neoscytalidiumdimidiatum es un hongo dematiáceo oportunista perteneciente a la clase Dothideomycetes.Caso clínicoPresentamos un caso de feohifomicosis cerebral por N. dimidiatum posterior a infección por COVID-19 en un paciente iraní de 32 años de edad. El microorganismo responsable fue identificado por citopatología, métodos rutinarios de laboratorio y secuenciación del ADN del espaciador transcrito interno (ITS) del ADNr. Aparte de las complicaciones asociadas a la COVID-19 y al uso de corticoides, el enfermo no presentaba enfermedades subyacentes. Los síntomas indicativos de infección fúngica fueron observados dos semanas después de que el paciente recibiera el alta hospitalaria por la COVID-19. La resonancia magnética cerebral mostró una infección multifocal en el sistema nervioso central. El retraso en la identificación del hongo responsable y, consecuentemente, en la instauración del tratamiento antifúngico con anfotericina B, pudo afectar a la evolución del paciente, ya que este finalmente falleció.ConclusionesA pesar de la escasa incidencia de las infecciones por N. dimidiatum, este caso debe alertarnos sobre su existencia para instaurar así el tratamiento antifúngico conveniente a la mayor brevedad.

RESUMO

PURPOSE: Cerebral phaeohyphomycosis is a rare and fatal fungal infection of the central nervous system (CNS) caused by dematiaceous fungi. The aim of this study was to analyse the clinico- radiological presentation, pathology and outcome of cerebral phaeohyphomycosis and discuss the relevant literature. PATIENTS AND METHODS: Data of 7 patients diagnosed with cerebral phaeohyphomycosis and managed at our institute between 2014 and 2020 was collected and reviewed retrospectively. The diagnosis was established after surgery on KOH mount, Sabouraud dextrose agar, frozen section or histopathology. The clinical, radiological and pathological characteristics along with outcomes were analysed. RESULTS: Three patients with underlying comorbidities [chronic renal failure-2 and haematological malignancy -1] presented with brain abscess. The remaining 4 had no comorbidities. Two of them mimicked cystic glioma and one patient presented as intraventricular tumour. Another patient on anti- tubercular treatment for suspected pulmonary tuberculosis presented with encephalitis. Histopathology in all patients showed diffuse micro abscesses with coarse and reactive gliosis in the adjacent brain parenchyma and chronic lymphomononuclear inflammation without angioinvasion or vasculitis. Four showed granuloma formation. Antifungals were started after diagnosis. Six out of seven patients died and one was lost to follow up. CONCLUSION: Cerebral phaeohyphomycosis presents as abscesses in immunocompromised patients and mimics tumours in immunocompetent patients. KOH mount and frozen section examination is simple yet effective tool for establishing early diagnosis. Overall, the prognosis is dismal. Administering antifungals early in the course of management along with aggressive surgical excision may improve outcomes.

RESUMO

BACKGROUND: Fungal brain abscesses in immunocompetent patients are exceedingly rare. Cladophialophora bantiana is the most common cause of cerebral phaeohyphomycosis, a dematiaceous mold. Radiological presentation can mimic other disease states, with diagnosis through surgical aspiration and growth of melanized fungi in culture. Exposure is often unknown, with delayed presentation and diagnosis. CASE PRESENTATION: We present a case of cerebral phaeohyphomycosis in a 24-year-old with no underlying conditions or risk factors for disease. He developed upper respiratory symptoms, fevers, and headaches over the course of 2 months. On admission, he underwent brain MRI which demonstrated three parietotemporal rim-enhancing lesions. Stereotactic aspiration revealed a dematiaceous mold on staining and the patient was treated with liposomal amphotericin B, 5-flucytosine, and posaconazole prior to culture confirmation. He ultimately required surgical excision of the brain abscesses and prolonged course of antifungal therapy, with clinical improvement. CONCLUSIONS: Culture remains the gold standard for diagnosis of infection. Distinct microbiologic findings can aid in identification and guide antimicrobial therapy. While little guidance exists on treatment, patients have had favorable outcomes with surgery and combination antifungal therapy. In improving awareness, clinicians may accurately diagnose disease and initiate appropriate therapy in a more timely manner.

RESUMO

Chaetomium sp. is a mold, member of the phylum Ascomycota. Clinical disease in humans is rare, particularly in children, for which only five cases have been reported. We report a 7-months-old female patient with a diagnosis of visceral heterotaxy syndrome who was admitted to a private center in Mexico. After two episodes of focal myoclonic seizure, a brain magnetic resonance imaging (MRI) revealed a right porencephalic cyst and a right frontal abscess with ventriculitis. Seventy-two hours after temporal abscesses drainage procedure, the culture showed a rapidly growing pale white fungal colony. Sequencing of internal transcribed spacer (ITS) and D1/D2 led to the identification of Chaetomium strumarium. Although Chaetomium sp. is a rare fungal infection in humans, clinicians should consider it as a plausible etiologic agent that can form brain abscess.

RESUMO

Cerebral phaeohyphomycosis is a rare but serious fungal infection of the central nervous system caused by dematiaceous septate fungi characterized by the presence of melanin-like pigment within the cell wall that is a pale brown to black. It is associated with poor prognosis despite aggressive treatment. We report a previously well 3-year boy with cerebral phaeohyphomycosis who had subacute meningoencephalitic presentation with refractory raised intracranial pressure and had fatal outcomes. The diagnosis was confirmed by histopathological examination of brain tissue obtained by brain biopsy.

RESUMO

We report this rare case of cerebral phaeohyphomycosis in a previously healthy Chinese boy, who was found to have caspase recruitment domain family member 9 (CARD9) deficiency. Initial radiological features suggested a neoplastic cerebral lesion, while histopathological examination supplemented by internal transcribed sequencing (ITS) of cerebral tissue confirmed the diagnosis of phaeohyphomycosis. He was treated with intravenous (IV) liposomal amphotericin B and voriconazole, guided by plasma and cerebrospinal fluid (CSF) level monitoring at drug initiation. At the 1 year follow-up, the patient demonstrated near complete neurological and radiological recovery.

RESUMO

We report a case of cerebral phaeohyphomycosis, a fungal brain infection due to a dark (dematiaceous) fungi in a 6-year-old French Guyanese boy. The child presented fever and drowsiness due to several paraventricular brain abscesses. Neurological surgeries were performed to reduce intracranial hypertension and to obtain abscess biopsies. Mycological cultures of intraoperative samples led to the diagnosis of cerebral phaeohyphomycosis due to Cladophialophora bantiana. The patient neurological status deteriorated and remained critical after several weeks of combination antifungal therapy with voriconazole 8mg/kg/day, liposomal amphotericin B 10mg/kg/day and flucytosine 200mg/kg/day. A complete surgical resection was not possible because of multiple small abscesses. A multidisciplinary ethical staff decided on home medical care with palliative ventriculoperitoneal shunt, nasogastric feeding and analgesics. One year later, the patient's neurological condition had improved and cerebral lesions had regressed, while he had not received any antifungal treatment but only traditional medicines. Cerebral phaeohyphomycosis are rare diseases affecting immunocompromised but also apparently non-immunocompromised patients, as in this case. A complete surgical resection is not always possible and mortality rates are high in spite of treatments with a combination of antifungals. The diagnosis may be difficult because of these dematiaceous fungi's slowly growing and their potential pathogenicity for laboratory staff.

RESUMO

Cerebral feohifomycosis are severe infections caused by dematiaceous fungi. Cladophialophora bantiana is one of the most commonly isolated species; it has central nervous system tropism and it often manifests as a brain abscess in immunocompetent patients. In immunocompromised patients, it can lead to brain abscesses and disseminated infections. Despite the availability of broad-spectrum antifungal drugs, it is a must to perform surgical management, in addition to drug therapy. However, mortality is high. The diagnostic approach must be invasive to establish a timely diagnosis and direct treatment based on culture and susceptibility tests. We report a case of brain abscess caused by C. bantiana in an immunosuppressed patient who was treated with surgical resection and voriconazole with an adequate response to therapy and without neurological sequels.


Las feohifomicosis cerebrales son infecciones graves causadas por mohos dematiáceos, entre los cuales Cladophialophora bantiana es una de las especies más comúnmente aislada. Esta tiene tropismo por el sistema nervioso central y frecuentemente produce abscesos cerebrales en pacientes inmunocompetentes; además, en los inmunocomprometidos también puede ocasionar infección diseminada. Pese a la disponibilidad de medicamentos antifúngicos de amplio espectro, a menudo se requiere también la intervención quirúrgica; de todas maneras, la mortalidad es elevada. El diagnóstico debe hacerse interviniendo para tomar la muestra y hacer el cultivo y las pruebas de sensibilidad. Se presenta aquí el caso de un paciente con trasplante renal que presentó un absceso cerebral por C. bantiana, el cual se extrajo mediante resección quirúrgica.

RESUMO

Posaconazole diffusion has been documented in various organs, which contrasts with the scarce data available for the human central nervous system (CNS). We analyzed posaconazole concentrations in plasma and multiple CNS specimens taken from a patient who received posaconazole because of cerebral phaeohyphomycosis. Low posaconazole concentrations were obtained in CNS specimens, with sample-to-plasma ratios between 5% and 22%. This case highlights the role of neurosurgery during cerebral phaeohyphomycoses, even those caused by posaconazole-susceptible black fungi.

RESUMO

Resumen Las feohifomicosis cerebrales son infecciones graves causadas por mohos dematiáceos, entre los cuales Cladophialophora bantiana es una de las especies más comúnmente aislada. Esta tiene tropismo por el sistema nervioso central y frecuentemente produce abscesos cerebrales en pacientes inmunocompetentes; además, en los inmunocomprometidos también puede ocasionar infección diseminada. Pese a la disponibilidad de medicamentos antifúngicos de amplio espectro, a menudo se requiere también la intervención quirúrgica; de todas maneras, la mortalidad es elevada. El diagnóstico debe hacerse interviniendo para tomar la muestra y hacer el cultivo y las pruebas de sensibilidad. Se presenta aquí el caso de un paciente con trasplante renal que presentó un absceso cerebral por C. bantiana, el cual se extrajo mediante resección quirúrgica. El paciente recibió tratamiento con voriconazol, con adecuada respuesta, mejoría y sin secuelas neurológicas.


Abstract Cerebral feohifomycosis are severe infections caused by dematiaceous fungi. Cladophialophora bantiana is one of the most commonly isolated species; it has central nervous system tropism and it often manifests as a brain abscess in immunocompetent patients. In immunocompromised patients, it can lead to brain abscesses and disseminated infections. Despite the availability of broad-spectrum antifungal drugs, it is a must to perform surgical management, in addition to drug therapy. However, mortality is high. The diagnostic approach must be invasive to establish a timely diagnosis and direct treatment based on culture and susceptibility tests. We report a case of brain abscess caused by C. bantiana in an immunosuppressed patient who was treated with surgical resection and voriconazole with an adequate response to therapy and without neurological sequels.
