title: Primary leiomyosarcoma of gallbladder seen on computed tomography and ultrasound.
abstract: Neoplasms of the gallbladder are relatively rare and their preoperative diagnosis that much rarer; leiomyosarcoma of the gallbladder is one of the most infrequent types. The authors had the opportunity to diagnose such a neoplasm preoperatively (although the histological diagnosis was not made). The ultrasound and computed tomographic appearance has not been published before. Leiomyosarcoma showed a dilated gallbladder with an irregularly thickened wall and a polypoid protrusion into the lumen.
