CT manifestations of peritoneal leiomyosarcomatosis

CT findings of six patients with pathologically proved malignant peritoneal disease secondary to leiomyosarcomas were reviewed. Peritoneal implants, hepatic metastases and ascites were found in five, five and two, of the six patients, respectively. Neither lymphadenopathies, diffuse peritoneal mesenteric involvement, nor intralesional calcification were observed. Although infrequent, peritoneal leiomyosarcomatosis should be included in the differential CT diagnosis of carcinomatosis.
