We report a case of small bowel obstruction (SBO) caused by internal hernia from persistent attachment of a Meckel's diverticulum (MD) to the umbilicus by the obliterated omphalomesenteric duct that was diagnosed by multidetector CT and confirmed during laparoscopic surgery. Although clinical, pathological and radiological features of MD and its complications are well known, the diagnosis of MD is difficult to establish preoperatively. CT findings that allow the diagnosis of this very unusual cause of SBO are presented here with laparoscopic surgery correlation.
