A black mould death: A case of fatal cerebral phaeohyphomycosis caused by Cladophialophora bantiana.

ABSTRACT: Cladophialophora bantiana is a neurotropic mould and primary cause of cerebral phaeohyphomycoses, which presents with brain abscesses in both immunocompromised and immunocompetent individuals. It is associated with high mortality due to delay in diagnosis and absence of standardised therapy. We present a case of fatal cerebral phaeohyphomycosis in a 67-year-old Caucasian man. Diagnosis was achieved by histopathological examination of brain tissue followed by conventional culture and molecular identification. We highlight diagnostic and treatment challenges involved.

Fatal cerebral phaeohyphomycosis caused by Cladophialophora bantiana mimicking tuberculous brain abscess.

Project description:IntroductionCladophialophora bantiana, a neurotropic phaeoid fungus, is the primary agent of cerebral phaeohyphomycosis. The disease more commonly affects immunocompetent males and is associated with a high mortality rate.Case reportWe report a case of brain abscess caused by Cladophialophora bantiana in a 50-year-old immunocompetent male who presented with headache for two months, weakness of both lower limbs for 15 days, and altered sensorium and aphasia for one day. Contrast-enhanced MRI of the brain showed multiple coalescent abscesses in the right basal ganglia and corpus callosum. Based on clinical and radiological suspicion of tuberculoma, treatment with antitubercular drugs was initiated. A month after discharge, the patient was re-admitted with history of loss of consciousness, altered sensorium, respiratory distress and aphasia. Brain CECT revealed multiple ring-enhancing lesions in the right basal ganglia with mass effect and a leftward midline shift. The patient underwent craniotomy and evacuation of abscess. Direct microscopy of pus aspirated from the lesions showed pigmented septate fungal hyphae, which was identified as C. bantiana in fungal culture. The patient was administered intravenous liposomal amphotericin B and voriconazole. However, he died due to multiple organ failure on day 19 after surgery.ConclusionsFungal etiology should be considered in the differential diagnosis of intracranial space occupying lesions, regardless of the host immune status. An early diagnosis, together with aggressive medical and neurosurgical interventions are imperative for improving the survival in such patients.

A rare case of fatal cerebral phaeohyphomycosis caused by Cladophialophora bantiana in an immunocompetent individual in India.

Project description:Background and purposeHerein, we describe a rare case of fatal cerebral phaeohyphomycosis by Cladophialophora bantiana in an immunocompetent individual without any underlying risk factors.Case reportA 55-year-old female presented with a short history of fever for 1 month, as well as headache, sudden onset of right-sided upper and lower limb weakness, and loss of speech for 10 days. Contrast-enhanced magnetic resonance imaging scan revealed large, peripherally enhancing, well-defined, cystic, space- occupying, axial lesion in the left parietal lobe with a mass effect. The patient was subjected to craniotomy, and the drained pus revealed pigmented septate hyphae in potassium hydroxide mount examination, which was identified as Cladophialophora bantiana. The patient was started on amphotericin B and voriconazole. However, she developed acute respiratory infection leading to multi-organ failure and death on day 27 post-operation.ConclusionIn the absence of comparative trials owing to the rarity of the disease, the radical resection of lesion, drainage of pus, and prolonged targeted antifungal therapy with close postoperative radiological surveillance are the therapeutic measures of choice for patients with brain abscess caused by phaeoid fungi.

First case of systemic phaeohyphomycosis due to Cladophialophora bantiana in Slovakia.

Project description:INTRODUCTION:Melanized or dematiaceous fungi are associated with a wide variety of infectious syndromes. Cladophialophora bantiana is one of the most common and dangerous neurotropic fungi, able to cause brain abscess and disseminated infection. CASE PRESENTATION:We report a new case of phaeohyphomycosis brain abscesses caused by C. bantiana in Slovakia. The patient was a 63-year-old man having undergone heart transplantation, with dyspnoea, left-sided bronchopneumonia and fevers. CT (computed tomography) and MRI (magnetic resonance imaging) of the brain revealed numerous abscesses. Bacterial infection was proven by neither the growth of bacteria in culture nor the presence of bacterial antigens. Direct microscopy of the pus from the brain abscess showed Gram-positive hyphae. The isolate was finally identified as C. bantiana based on morphological and physiological features, and on DNA sequence analysis. CONCLUSION:In spite of appropriate therapy, neurological complications and accelerated respiratory insufficiency resulted in the patient's death. Concerning clinical manifestation of the brain phaeohyphomycosis that can sometimes be a problem to distinguish from malignancy, physicians should also assume infection caused by this serious pathogen.

Eumycetoma caused by Cladophialophora bantiana in a dog.

Project description:We report a case of eumycetoma due to Cladophialophora bantiana in a 3-year-old male Siberian Husky living in France. The dog presented a tumefaction on the thorax and deformity of the second and third subjacent ribs, which were surgically removed. Macroscopic black granules were visible on the ribs, and direct microscopic examination revealed their fungal origin. Cultures yielded pure colonies of C. bantiana. The identification of the causative agent was confirmed after amplification and sequence analysis of fungal internal transcribed spacers 1 and 2 and 5.8S ribosomal DNA regions. Surgery and antifungal treatment with oral itraconazole associated with flucytosine allowed apparent cure after a 10-month follow-up. Envenomation with pine processionary caterpillars (Thaumetopoea pityocampa) and subsequently intensive corticotherapy were considered as possible predisposing factors. This is, to the best of our knowledge, the first case in which C. bantiana is identified as the causative agent of eumycetoma.

Genomic Analyses of Cladophialophora bantiana, a Major Cause of Cerebral Phaeohyphomycosis Provides Insight into Its Lifestyle, Virulence and Adaption in Host.

Project description:Cladophialophora bantiana is a dematiaceous fungus with a predilection for causing central nervous system (CNS) infection manifesting as brain abscess in both immunocompetent and immunocompromised patients. In this paper, we report comprehensive genomic analyses of C. bantiana isolated from the brain abscess of an immunocompetent man, the first reported case in Malaysia and Southeast Asia. The identity of the fungus was determined using combined morphological analysis and multilocus phylogeny. The draft genome sequence of a neurotrophic fungus, C. bantiana UM 956 was generated using Illumina sequencing technology to dissect its genetic fundamental and basic biology. The assembled 37.1 Mb genome encodes 12,155 putative coding genes, of which, 1.01% are predicted transposable elements. Its genomic features support its saprophytic lifestyle, renowned for its versatility in decomposing hemicellulose and pectin components. The C. bantiana UM 956 was also found to carry some important putative genes that engaged in pathogenicity, iron uptake and homeostasis as well as adaptation to various stresses to enable the organism to survive in hostile microenvironment. This wealth of resource will further catalyse more downstream functional studies to provide better understanding on how this fungus can be a successful and persistent pathogen in human.

Cladophialophora Bantiana : A Rare Intracerebral Fungal Abscess-Case Series and Review of Literature.

Project description:Background Intracerebral Cladophialophora bantiana may carry up to a 70% mortality rate despite advances in surgical resection capabilities and the use of both systemic and intrathecal antifungal treatments. Objectives The authors examined a retrospective case series of two patients with intracerebral infection from the rare, neurotropic fungus Cladophialophora bantiana and conducted a literature review to evaluate optimal therapies. Patients/Methods At our institution, the patients' cases presented with raised intracranial features of headache, visual field cut, and/or memory loss, with a correspondingly wide variety of radiological differential diagnoses. It was the microbiological, histopathological, and genomic identification of C. bantiana that ensured targeted, individualized patient therapies. Results and Conclusions Successful treatment depends on obtaining a complete surgical resection, an accurate microbiological diagnoses for mold identification, and an effective long-term, personalized antifungal treatment. Close radiographic surveillance is necessary to ensure complete eradication of pheoid fungi.
