ABSTRACT

<p><b>OBJECTIVE</b>To explore the diagnostic value of CT in midgut malrotation.</p><p><b>METHODS</b>The CT appearances of 16 patients with midgut malrotation were analyzed retrospectively.</p><p><b>RESULTS</b>The features of CT manifestation in 16 cases were as follows: (1) Horizontal part of duodenum could not reach medioventral line or could reach it but encircled right-down behind the superior mesenteric artery(SMA). (2) Ectopic ileocecal junction. (3) Jejunum located in right-middle abdomen while ileum in left abdomen. (4) A clockwise or counterclockwise rotation of the superior mesenteric vein (SMV) around the SMA. (5) Mid-gut volvulus.(6)Accompanied by other malformations.</p><p><b>CONCLUSION</b>Ambulation of duodenum, location of the small intestine and colon as well as anatomical position of mesenteric vessels should be intensively observed in order to exclude midgut malrotation.</p>
