Abstract We report a case of chiasmitis caused by a rare nontuberculous mycobacterium in an immunocompromised patient. A 44-year-old man with a history of AIDS presented with recurrent vision loss and headache. Magnetic resonance imaging (MRI) demonstrated an enhancing mass involving the optic chiasm. Histopathologic and microbiological evaluation revealed infection with Mycobacterium haemophilum. While combination antimicrobial and steroid therapy contributed to improvement in his vision, the patient's symptoms recurred. Follow-up MRI showed extension of infection to the hypothalamus and leptomeninges, indicative of basilar meningitis. MRI is a valuable tool for early diagnosis of chiasmitis as well as for monitoring infection progression and treatment response.
