[Subphrenic Meckel's diverticulum as a differential diagnosis to Chilaiditi's syndrome].

Meckel's diverticulum (MD) occurs in 2-4% of the population and is the most common congenital abnormality of the gastrointestinal tract. A 67 year-old woman was admitted with acute abdomen. Abdominal X-ray showed pneumoperitoneum. During explorative laparoscopy a large perforated MD was found over the right hepatic lobe. CT-scans from an earlier admission revealed the MD but it was misinterpreted on that occasion. An MD in this place and in a person of this age is extremely rare. This case can primarily serve as differential diagnosis when CT-scans reveal mysterious subphrenic configurations.
