Non-neoplastic enterogenous submucosal cystic lesion of the colon

Abstract

Non-neoplastic enterogenous submucosal cystic lesions arise from the colonic or rectal wall, and more common ones include duplication cysts, lymphangiomas, and colitis cystic profunda [1]. An enterogenous cyst may detach itself from the intestinal wall and lie close to its point of origin, which may be in the intermuscular, submucosal, or subserosal layers of the intestinal wall. Accurate diagnosis of non-neoplastic enterogenous submucosal cystic lesions is difficult, and thus the preoperative diagnosis mainly depends on initial colonoscopy findings, which may provide information that supports the abnormal clinical findings [2].
