Right paraduodenal hernia: characteristic MDCT findings.

Right paraduodenal hernia is a very rare cause of abdominal pain. It can lead to bowel obstruction, ischemia, and perforation with a high mortality. A timely and correct diagnosis with a rapid diagnostic tool is mandatory. However, clinical diagnosis of right paraduodenal hernia is difficult for its nonspecific symptoms. Traditionally, paraduodenal hernia was diagnosed by small bowel series that was a time-consuming image study. We report a case of right paraduodenal hernia with pre-operative fast diagnosis by multidetector row computed tomography. Fortunately, the ischemic bowel loops were timely alleviated by reduction and resection was prevented.
