The ileosigmoid knot is an uncommon but life-threatening cause of closed loop intestinal obstruction. Its treatment is different from a simple volvulus in that it has to be operated upon immediately. Preoperative CT scan diagnosis and prompt treatment can lead to a good outcome. Findings of simultaneous ileal and sigmoid ischemia with non-ischemic colon interposed in between should, in an appropriate clinical setting, indicate this condition. The presence of the whirl sign, medially deviated distal descending colon and cecum, and mesenteric vascular structures from the superior mesenteric vessels that converge toward the sigmoid colon on CT scan help clinch the diagnosis.
