Abstract
Mesotheliomas are rare tumors arising from serosal linings of the major serous cavities. Five patients with peritoneal mesothelioma underwent a double contrast barium enema (DCBE) and ultrasonography (US) (2 patients),/computed tomography (CT) (3 patients) and/or magnetic resonance imaging (MRI) (3 patients). The diagnosis was confirmed at laparotomy. The radiologic pattern at DCBE is unspecific and consists of compression and dislocation of bowel loops by extrinsic masses. Mesenteric retraction and segmental stenosis may be present. In one patient DCBE was normal. US, CT and MRI findings are also unspecific but when combined with information obtained from DCBE the site and abdominal extension of the disease are well defined.
