Amebic abscesses resulting from hematogenous spread have occasionally been described in the brain. Cerebral amebiasis occurs in 0.6% of amebic liver abscess cases. Patients commonly present with the abrupt onset of nausea, vomiting, headache, and mental status changes. Computed tomography (CT) reveals irregular lesions without a surrounding capsule or enhancement. A tissue biopsy sample reveals the trophozoites. Progression can be very rapid, sometimes leading to death within 12-72 hours.
