[Peritoneal carcinomatosis. Review of CT findings in 107 cases]

CT findings of 107 patients with non lymphomatous malignant peritoneal disease were retrospectively evaluated. The most common malignancies encountered were ovarian neoplasms (46%), followed by gastric (14%) and colonic carcinomas (10%). In 12 cases (11%) the primary site was unknown. Peritoneal and extraperitoneal findings were evaluated. Signs most frequently observed were: peritoneal implants (82%), ascites (70%), mesenteric implants (65%) and omental involvement (52%). Appreciation of the spectrum of CT findings in peritoneal carcinomatosis is essential for an accurate evaluation of scans in patients with abdominopelvic malignancies.
