Grey Turner’s Sign

Abstract

Bluish discolouration of the flanks 24–48 h after an acute attack of pancreatitis is known as Grey Turner's sign. It is caused by subcutaneous haemorrhage from retroperitoneal blood vessels damaged by pancreatic enzymes released during an acute attack of pancreatitis. The image shows a classical presentation of Grey Turner's sign involving a large area of the left flank.
