Pseudo to pseudo connection: pseudoaneurysm draining into the pseudocyst causing pseudohaemobillia

Haemosuccus pancreaticus (HP) is an exceedingly rare cause of lower gastrointestinal (GI) bleed where pseudoaneurysm of the peripancreatic vessels ruptures into a pancreatic pseudocyst and blood travel through the pancreatic duct, thereby, draining into GI tract via the ampulla of Vater. 1 We present a case of 65-year-old African-American woman with a history of alcohol abuse presented with melena for 1 day. The contrast-enhanced CT of abdomen/pelvis showed peripancreatic vascular pseudoaneurysm with active haemorrhage. Angiography confirmed the diagnosis of HP and successful transcatheter embolisation was performed.
