Fatal granulomatous Acanthamoeba encephalitis mimicking a stroke, diagnosed by correlation of results of sequential magnetic resonance imaging, biopsy, in vitro culture, immunofluorescence analysis, and molecular analysis.

ABSTRACT

Amebic infections involving the central nervous system are rare and difficult to diagnose. Magnetic resonance imaging (MRI) at timed intervals may be helpful, where scans reveal enhancing lesions and increased signal. We report a unique case of granulomatous amebic encephalitis that was proven pathologically with progressive radiological findings on MRI.
