Huge Pancreatic Pseudocyst Presenting With a Specific Morphology, Which Expanded to the Pelvic Space

Abstract

A 46-year-old man with alcoholism was admitted to our hospital complaining of fever and abdominal distension. Abdominal computed tomography (CT) revealed a huge pancreatic pseudocyst which expanded to the pelvic space with bacterial infection. The pancreatic pseudocyst was divided into two parts, one in intra-abdominal space and another in the omental bursa. Because of the lower effectiveness of conservative therapy, we performed percutaneous catheter drainage (PCD) using two catheters. We carefully determined their position for high effectiveness of drainage and intra-cystic lavage treatment. The size of the pseudocyst decreased and disappeared without surgical therapy. Additionally, the follow-up CT at forty-five days after PCD showed that occlusion of splenic vein had occurred, but the occlusion improved spontaneously. We herein report a rare case of a huge pancreatic pseudocyst presenting with a specific morphology, because of its rarity and interesting clinical course.
