Amebic abscess of the brain.
Brain abscesses caused by Entamoeba histolytica were treated in two residents of New Jersey, neither of whom had traveled beyond the eastern United States. The diagnosis in Case 1 was confirmed by the presence of ameba in both brain and pituitary abscesses. An elevated indirect hemagglutination (IHA) titer of 1:4096 and response to specific treatment with metronidazole and chloroquin were the criteria for diagnosis in Case 2. The computerized tomographic appearance of an amebic abscess is that of a rapidly progressive lesion without reaction in the adjacent brain. Of the seven reported cures, all of the patients received appropriate chemotherapy. Five of the seven were operated upon.
