olvulus of the greater omentum in a right inguinal ernia. Answer to the e-quid ‘‘Unusual cause of cute abdominal pain’’

This 27-year-old man had surgery 3 years ago for a bilateral inguinal hernia. He reports rapidly progressive abdominal pain over the past week, with vomiting and a temperature of 37.8◦. Clinical examination found diffuse abdominal guarding with a reducible right inguinal hernia. The ultrasound showed an oval-shaped echogenic mass at the right flank, without any intraperitoneal effusion. The patient had CT of the abdomen and pelvis, with contrast product, in axial slices with sagittal reconstruction (Fig. 1).
