A Resected Primary Angiosarcoma of the Pancreas Presenting Aggressive Metastatic Liver Recurrence with Uncontrollable Intra-abdominal Bleeding: a Case Report

Abstract A 74-year-old man was diagnosed to have a pancreas head tumor (38mm × 32 mm) due to an obstructive jaundice. The patient presented an acute intrabiliary bleeding, while waiting for surgery. Thus, after a coil embolization of the gastroduodenal artery and the anterior/posterior pancreaticoduodenal artery an emergency pancreatoduodenectomy was performed. The patient suffered from grade B delayed gastric emptying, being discharged on postoperative day 33. The pathological diagnosis established was pancreatic angiosarcoma. The patient was re-admitted 4 days after discharge with a general malaise and the loss of appetite. A dynamic computed tomography (CT) and angiography revealed multiple liver metastases and a massive hemoperitoneum. Despite of transcatheter hepatic arterial embolization with gelfoam particles, the patient died 42 days after operation. Six patients with primary angiosarcoma of the pancreas have been reported in English literature so far and this is the first report of unique features of angiogram of multiple liver metastases. The present report allows a deeper knowledge about the aggressive behavior of angiosarcoma of the pancreas.
