Case Review: X-ray & CT of Cecal Volvulus - a podcast by Daniel J. Kowal, MD
from 2021-10-13T09:00
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.
