Cerebral abscess caused by Cladosporium bantianum infection--case report.

A 26-year-old woman currently treated for systemic lupus erythematosus with steroid therapy presented with sudden onset of right hemiplegia. Computed tomography of the brain showed a large frontoparietal ring-enhanced lesion with perifocal edema. Stereotactic aspiration of the lesion revealed Cladosporium bantianum. The size of the abscess did not reduce in spite of optimum antifungal treatment. The abscess was subsequently excised through a frontoparietal craniotomy. At follow up after 24 months, there was no recurrence of the abscess. Cerebral Cladosporium bantianum infection is usually refractory to antifungal agents and the prognosis is very poor. This patient had the longest survival period in a case of Cladosporium brain abscess so far reported.
