title: Radiologic evaluation of gastrointestinal leiomyosarcomatosis.
abstract: A 68-year-old woman who had previously undergone small intestinal resection because of leiomyosarcoma was referred to our clinic with epigastric pain. A double-contrast barium study and the subsequent abdominopelvic CT and abdominal MRI examinations demonstrated multiple extraluminal growing tumors arising from the walls of stomach, small bowel, and colon. A CT-guided aspiration biopsy revealed malignant mesenchymal tumor. The presence of disseminated intra-abdominal masses without concomitant ascites and invasion of tissue planes on CT in a patient operated on prior because of a leiomyosarcoma led to the diagnosis of gastrointestinal leiomyosarcomatosis. In this report we discuss the radiological approach to this rare entity.
