Granulomatous brain tumor caused by Acanthamoeba

Abstract

✓ A case of a previously healthy 7-year-old girl with a left frontoparietal tumor identified as an Acanthamoeba-induced granuloma is reported, and the literature on Acanthamoeba meningoencephalitis is reviewed. Unlike most reported cases, the Acanthamoeba central nervous system infection presented in this girl as a discrete tumor without meningeal involvement or diffuse encephalitis. A favorable outcome was obtained following total excision of the mass and treatment with ketoconazole.
