Objective: To discuss the value of spiral CT in diagnosing infantile intestinal malrotation.
Methods: The spiral CT findings and clinical data of 23 cases of operatively-confirmed infantile intestinal malrotation were retrospectively analyzed.
Results: Twenty-three cases of infantile intestinal malrotation were all diagnosed by SCT and confirmed by surgery. The main findings were as follows: whirlpool or concentric circle sign in mesenteric root with midgut volvulus (n = 16); duodenum assumed as "Z" or olecranon spur sign (n = 18); inverted transposition or vertical arrangement of superior mesenteric artery and vein (n = 13); abnormal sign of ileocecal junction and colon in right lower quadrant (n = 23).
Conclusion: Spiral CT scanning has an important value in the early diagnosis of infantile intestinal malrotation.
