RESUMO
There have been a few reported cases of pancreatic pseudocyst with involvement of adjacent structures including the stomach, duodenum, and even the mediastinum. An intrasplenic pancreatic pseudocyst is an uncommon complication of acute or chronic pancreatitis. We report a case of pancreatic pseudocyst with splenic involvement in a 69-year-old man with a review of literatures. Abdominal CT revealed a 4 cm sized cyst at the pancreatic tail which was extending into the splenic hilum and splenic parenchyma. Distal pancreatectomy and splenectomy was performed. Pathologic findings demonstrated a pseudocyst of pancreatic tail which communicated with the infacted splenic parenchyma. Also vasculitis, endothelial hyperplasia and medial calcification of the splenic artery were observed.
