Loop type cecal volvulus: Multidetector computed tomography (MDCT) findings.

A 67-year-old woman presented in the emergency room with abdominal pain for 2 hours. Physical examination showed abdominal distension and diffuse pain without signs of peritoneal irritation. A plain abdominal radiography showed distension of cecum located ectopically in the left upper quadrant, with little aeration of the distal colon. Given these findings, an intravenous contrast enhanced multidetector computed tomography (MDCT) was performed (Figs. 1-4). The cecum was markedly enlarged and dilated, twisted and inverted, occupying the left hypochondrium. The terminal ileum was twisted also. These results were very suggestive of loop type cecal volvulus.
