Abstract
Cerebral phaeohyphomycosis refers to central nervous system infection by dematiaceous mould or by dark walled fungi which contain the dark pigment melanin in their cell wall which adds to the virulence of fungus. These dematiaceous fungi can cause a variety of central nervous infections including invasive sinusitis, brain abscess, meningitis, myelitis and arachnoiditis. Cladophialophora bantiana among these dematiaceous fungi is the most common cause of brain abscess in immunocompetent and immunocompromised individuals and is known to occur worldwide though is predominantly reported from subtropical regions especially the Asian subcontinent. It is difficult to differentiate these abscesses radiologically from high-grade gliomas, primary central nervous system lymphoma or other infections including toxoplasmosis, nocardiosis, tuberculosis and listeriosis. We describe a 19-year-old male patient with a cerebral abscess caused by C. bantiana where the diagnosis could be suspected by typical MR spectroscopic findings and by identifying the fungus from a lymph node biopsy.
