US and CT findings of rectal amebian abscess.

Abstract

An interesting case of rectal amebic abscess is presented. Ultrasound and CT images provided the diagnosis of a cystic intramural mass at the rectal wall of a young man, who complained of pelvic pain, constipation, and fever. His clinical history of amebiasis and the finding of trophozoids and cysts at the stool swap confirmed the diagnosis. Intravenous metronidazole therapy cured the disease and led to total disappearance of the mass, and clinical well-being.
