Methods: We studied the ocular manifestations of an 11-year-old boy with retinitis. Biomicroscopy, ophthalmoscopy, and fundus photography were done. Magnetic resonance imaging of the brain was performed. A vitreous biopsy was subjected to viral, bacterial, and fungal cultures. Results: Vitreous culture grew C. atrobrunneum. Magnetic resonance imaging showed multiple cerebral lesions consistent with an infectious process. The patient was given intravenous voriconazole and showed improvement of the ocular and central nervous system lesions. Conclusion: We report a case of central nervous system and ocular lesions by C. atrobrunneum. The retinitis was initially misdiagnosed as cytomegaloviral retinitis. Vitreous biopsy helped in the early diagnosis and prompt treatment of a life- and vision-threatening infection. This report presents a case of Chaetomium atrobrunneum retinitis in a patient with Hodgkin's lymphoma. Patient was initially diagnosed as a case of Cytomegalovirus retinitis. Vitreous biopsy helped in the recognition of the fungus and the administration of specific antifungal therapy which was life saving. © 2010 Ophthalmic Communications Society, Inc.
