CT Features of Metastatic Linitis Plastica to the Rectum in Patients with Peritoneal Carcinomatosis

Abstract

OBJECTIVE: We examined the CT features of 22 patients with metastatic linitis plastica to the rectum. CONCLUSION: Metastatic linitis plastica to the rectum should be considered when CT shows a long segment of circumferential rectal wall thickening, especially in patients with peritoneal carcinomatosis from gastric cancer. In such patients, CT helps avoid unnecessary extensive surgery.
