Pancreatic cyst: pseudocyst or neoplasm? Pitfalls in endoscopic retrograde cholangiopancreatography diagnosis.

摘要: Pancreatic pseudocysts represent the majority of cystic lesions, and can usually be differentiated from neoplasms, which have malignant potential. Endoscopic retrograde cholangiopancreatography (ERCP) help in solving diagnostic dilemmas. When ERCP demonstrates cyst communication with pancreatic duct, diagnosis pseudocyst is secure. There are exceptions, however, as reported these two case reports. A retrospective chart review was conducted patients undergoing distal pancreatectomy 2008 to 2009 for lesions communicating main duct on ERCP. Both were women (ages 37 42) a history chronic abdominal pain pancreatitis. Radiologic imaging showed tail. demonstrated communication. endoscopic management failed, surgical therapy undertaken. underwent splenectomy. Pathologic findings mucinous cystadenoma. The conventional wisdom that benign not always wise. As seen this series, cystadenomas erode into duct.
