ABSTRACT
Leiomyomatosis peritonealis disseminata is usually asymptomatic or mimics widespread malignancy; acute presentation is rare. We describe a patient with right iliac fossa and lower abdominal pain. Two masses were detected via computed tomography, but at surgery, one of these implanted leiomyomas had undergone acute omental torsion. This case illustrates a rare complication of omental leiomyoma torsion clinically mimicking acute appendicitis.
