What imaging finding is classically associated with cecal volvulus?

• A. Free air
• B. Air-fluid levels
• C. Coffee bean sign
• D. Apple core lesion

Answer: (C)

Cecal volvulus is a type of bowel obstruction that occurs when the cecum twists around itself and its mesenteric attachment. This condition is most commonly associated with the classic "coffee bean sign" on imaging studies, particularly X-rays. The coffee bean sign refers to the characteristic appearance of distended bowel loops, resembling a coffee bean, created by the gas-filled cecum that becomes twisted. In cases of cecal volvulus, the twisted cecum leads to obstruction, and the resulting accumulation of gas and fluid within the dilated bowel creates a distinct shape that aids in diagnosis. This finding is usually best visualized on a flat abdominal radiograph, where the arrangement of the bowel can mimic the outline of a coffee bean. Other imaging findings, while relevant in different gastrointestinal emergencies or conditions, are not commonly associated with cecal volvulus. For example, free air typically indicates perforation, air-fluid levels can be seen in various types of obstruction, and the apple core lesion is associated with colonic carcinoma rather than volvulus. Thus, the coffee bean sign is the classic and most specific radiographic finding used to identify cecal volvulus.
