膵仮性嚢胞は、急性膵炎と慢性膵炎の両方でよくみられる合併症である。膵仮性嚢胞の合併症としては、腹部大血管の圧迫、胃や十二指腸の狭窄、総胆管の狭窄によるコレスタシス、感染症、嚢胞への出血などがあります。また、膵仮性嚢胞は膵臓周辺に発生することが多いが、脾臓、肝臓、横結腸、前・後胸郭、後腹膜、縦隔などの隣接内臓への進展はまれである。ここでは，透析患者に出血を伴った非定型の広範囲膵臓仮性嚢胞を発症したまれな症例を報告する．

Pancreatic pseudocysts are a common complication of both acute and chronic pancreatitis. The complications of pancreatic pseudocysts include compression of abdominal great vessels, gastric or duodenal stenosis, cholestasis due to stenosis of common bile duct, infection, and hemorrhage into the cyst. Moreover, pancreatic pseudocysts most commonly occur around the pancreas; however, extension into the adjacent viscera including spleen, liver, transverse colon, anterior or posterior pararenal space, retroperitoneum and mediastinum does occur infrequently. Here, we report a rare case of atypical extensive pancreatic pseudocyst with hemorrhage in a hemodialysis patient.
