RADIOLOGIC EVALUATION OF GASTROINTESTINAL LEIOMYOSARCOMATOSIS

A 68-year-old woman who had previously undergone small intestinal rese ction because of leiomyosarcoma was referred to our clinic with epigas tric pain. A double-contrast barium study and the subsequent abdominop elvic CT and abdominal MRI examinations demonstrated multiple extralum inal growing tumors arising from the walls of stomach, small bowell, a nd colon. A CT-guided aspiration biopsy revealed malignant mesenchymal tumor. The presence of disseminated intra-abdominal masses without co ncomitant ascites and invasion of tissue planes on CT in a patient ope rated on prior because of a leiomyosarcoma led to the diagnosis of gas trointestinal leiomyosarcomatosis. In this report we discuss the radio logical approach to this rare entity.
