This sign takes 24–48 hours to appear and can predict acute pancreatitis, with mortality rising from 8–10% to 40%. It may be accompanied by Grey Turner's sign[3] (bruising of the flank), which may then be indicative of pancreatic necrosis with retroperitoneal or intra-abdominal bleeding.
Causes
Causes include:
acute pancreatitis, where methemalbumin formed from digested blood tracks around the abdomen from the inflamed pancreas
