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.
췌장염 환자의 경우에 췌장 내에 동반된 낭종성 병변이 관찰된다면 보통 췌장의 가성낭종으로 생각되어 보존적 치료와 경과관찰하는 경우가 많다. 저자들은 급성 췌장염으로 내원한 환자에서 이에 동반된 췌장의 낭성병변에 대해 가성낭종으로 추정진단하고 12개월 동안 추적관찰했으나 그 낭성병변이 점액성 낭성종양으로 최종 진단된 증례를 경험하여 문헌고찰과 함께 보고한다.
