[Cerebral miliary granulomatosis with Histoplasma capsulatum in an HIV seronegative patient].

A 51 year old patient who worked in Africa for eight years, presented twelve years later a progressive ataxia associated with headaches. Neuroimaging studies done after a partial complex seizure demonstrated multiple supra and sub-tentorial cortical ring enhancing lesions. Histoplasma capsulatum histoplasmosis was found on histological examination of brain biopsy and confirmed by isolation of the fungus. Medical treatment with intravenous amphotericin B followed by oral itraconazole (400 mg per day) improved both clinical and radiological status. This observation of cerebral histoplasmosis is rather unusual for a seronegative HIV patient in a non endemic area.
