On plain abdominal films, the sigmoid volvulus forms an inveed U-shaped structure with the twisted sigmoid loops lying adjacent and having an oval appearance called the "coffee bean" sign. On barium enema examination, tapered obstruction of the sigmoid colon is found. Ref: Ott D.J. (2011). Chapter 10. Gastrointestinal Tract. In M.Y. Chen, T.L. Pope, D.J. Ott (Eds), Basic Radiology, 2e.
