title: Amebic meningoencephalitis: spectrum of imaging findings.
abstract: Primary amebic meningoencephalitis and granulomatous amebic meningoencephalitis are central nervous system infections caused by free-living amebae. We describe the neuroimaging findings in 5 such cases on CT and MR imaging. A spectrum of findings was seen in the form of multifocal parenchymal lesions, pseudotumoral lesions, meningeal exudates, hemorrhagic infarcts, and necrosis in the brain. Familiarity with the imaging findings is important for the diagnosis and management of this nearly universally fatal disease.
