Granulomatous amebic encephalitis in an AIDS patient.
A 39-year-old man with AIDS died after developing a variety of neurologic symptoms and signs. CT showed multiple enhancing lesions in the cerebral hemispheres and cerebellum. Postmortem examination revealed parenchymal hemorrhagic and necrotizing lesions with a thrombo-occlusive vasculitis due to Acanthamoeba, which was typed as Acanthamoeba group 2, probably A rhysodes, by immunofluorescence.
