Phaeohyphomycosis of the central nervous system is rare but typically associated with high mortality. Treatment has not been standardized, but the combination of antifungal chemotherapy with surgical debridement is recommended. We report a 73-year-old, retired, male timber merchant with acute meningitis caused by Cladosporium sphaerospermum. The patient, who had well-controlled type 2 diabetes mellitus, presented with fever and weakness of the lower limbs. No brain abscess was apparent by cranial computed tomography. C. sphaerospermum was isolated from the cerebral spinal fluid and identified based on both morphology and DNA sequencing. He was treated with combination antifungal chemotherapy with amphotericin B and voriconazole for 28 days, followed by voriconazole monotherapy for 46 days. To date, the patient has recovered without significant sequelae. This patient represents the first reported case of cerebral phaeohyphomycosis caused by C. sphaerospermum. Moreover, the therapy was successful for totally less than 3 months of treatment duration.
