Case of the Week: Cecal Volvulus (X-ray & CT)

Listen Later

In this inaugural case of the week radiology lecture, we discuss the imaging appearance of cecal volvulus!

Key points include:

  • Cecal volvulus occurs when there is twisting of cecum around the mesentery with proximal large bowel obstruction.
  • Cecum normally <9 cm, rest of large bowel <6 cm.
  • Topogram (scout view) extremely helpful.
  • Vector typically points towards LUQ, but instead of worrying about vector direction, look for proximal dilated small bowel (as opposed to large bowel) to differentiate from sigmoid volvulus.
  • Complications include pneumoperitoneum = bowel perforation (Rigler’s sign, falciform ligament sign) and pneumatosis = cecal ischemia.
