We report the first case of granulomatous amebic encephalitis caused by Acanthamoeba in a previously healthy farmer in Taiwan who fell into a ditch. The DNA amplicons of amebas identified by polymerase chain reaction in the cerebrospinal fluid specimen and the ditch water specimens were identical and shared strong homology with A. castellanii . He survived after treatment with amphotericin B, rifampin, and corticosteroids.
