Computed tomographic findings of small-bowel volvulus.

Computed tomographic examinations of two cases of small-bowel volvulus were reviewed. At laparotomy, both cases were proved to be secondary to adhesions. CT examinations showed focal, wedge-shaped, edematous mesentery with trapped fluid between mesenteric folds radiating toward the site of torsion. One case showed the superior mesenteric vein spiraling around the superior mesenteric artery. At laparotomy, affected small-bowel loops showed ischemia in both cases. CT performed in patients with acute abdomen may show findings suggestive of small-bowel volvulus.
