Coffee bean sign detected by visual inspection

An 87-year-old Japanese male patient presented with abdominal distension and pain lasting for half a day. On physical examination, two distended ridges running parallel from upper right to lower left were seen in the abdomen (Figure 1A). This pattern of distension looked like radiological “coffee bean sign.” The diagnosis of sigmoid volvulus was soon suspected, which was confirmed by abdominal computed tomography scan (Figure 1B). Endoscopic reduction was performed, and the symptoms diminished.
