Abstract
- Pancreatic cystic lesions include retention cysts (congenital cysts), pseudocysts, and cystic neoplasms. Pancreatic cystic neoplasms have recently been diagnosed more commonly, possibly due to advances in imaging and widespread screening programs. Cystic neoplasms of the pancreas account for 10-20% of pancreatic tumors. Mucinous cystic neoplasms (MCN) and intraductal papillary mucinous neoplasms are regarded as premalignant lesions, whereas serous cystadenoma is not. In the clinical setting of acute pancreatitis, pancreatic cystic lesions are usually diagnosed as pseudocysts. However, cystic neoplasms of the pancreas should be considered in the differential diagnosis of pancreatic cysts, even in patients with a history of pancreatitis. In the Korean literature, MCN combined with acute pancreatitis has rarely been reported. Here, we report a case of MCN presenting with acute pancreatitis in a 22-year-old female, which was initially misdiagnosed as pancreatic pseudocyst.
