[Abstract]　Mesentery is one of the important structure of peritoneal cavity ,which includes mesentery of small intestine ,transverse mesocolon and sigmoid mesocolon.The recognition of CT manifestations of normal anatomy and pathology of mesentery is helpf ul to the correct diagnosis of abdominal diseases such as inflammatory ,cyst ,tumor ,vascular ,trauma and other diseases.

肠系膜为腹腔内的重要结构之一,是由双层腹膜形成的皱襞,将肠管悬吊在腹后壁,并使其保持有一定的活动性,它包括小肠系膜、横结肠系膜、乙状结肠系膜等。肠系膜一方面为腹腔内器官病变(炎性、肿瘤等)扩散提供了一个桥梁,另一方面对腹腔的积液、脓肿起分隔作用。此外,由于肠系膜内有
