The spectrum of angiographic findings of abdominal leiomyosarcoma in 33 cases is presented, and the value of angiography in the diagnosis and management of such patients is discussed. Angiographic features of abdominal leiomyosarcomas are different depending upon the site of origin. Small bowel lesions are hypervascular, and those in the stomach and colon moderately vascular. Well circumscribed masses with enlarged feeding arteries and draining veins form the predominant presentation of small bowel leiomyosarcoma. In the retroperitoneum these neoplasms are usually hypovascular to moderately vascular, and displacement of major vessels, particularly the inferior vena cava, is the most common angiographic finding. Bladder leiomyosarcoma can be either moderately vascular or hypervascular. Vascularity of metastases is usually similar to that of the primary lesion.

Small bowel neoplasms are very uncommon, especially leiomyosarcoma of the small bowel. Therefore, there is often a delay before small bowel leiomyosarcoma is diagnosed and treatment is started. A 60-year-old Caucasian male was admitted to our hospital with progressive melena. Gastroscopy and colonoscopy did not reveal the cause of the melena, but magnetic resonance imaging showed a jejunal tumor. After laparoscopic resection, the tumor appeared to be a grade 2 leiomyosarcoma. Small bowel neoplasms can be accurately detected by magnetic resonance enterography or wireless capsule endoscopy. Treatment almost always consists of resection of the primary tumor and its metastases. The role of chemo- and radiotherapy is not yet clear and prognosis remains very poor, with low five-year survival rates.
