Isolated primary intracerebral mycetoma: presenting as a mass lesion in a patient with prostate cancer and multiple myeloma.

We report a patient with a history of prostate cancer and multiple myeloma, with a solitary indolent intracerebral mass lesion without any constitutional symptoms and minimal neurologic symptoms. The radiographic appearance of the lesion was that of a tumor but resection revealed a mycetoma, consistent with Aspergillus. A brief review of the literature discusses the rarity, presentation, diagnosis, and management of primary intracerebral mycetomas.
