| [ Summary ] |
There has not been an increased consensus on the proper treatment of intraductal papillary-mucinous tumors (IPMT). It is important to select the appropriate diagnostic techniques. Because of abundant mucous secretion, the pancreatic duct is dilated and the mural nodule is located in the pancreatic duct. Diagnostic images that can detect these findings are useful. US and CT are non-invasive and useful for screening MRCP, ERCP, EUS and IDUS are performed to confirm the diagnosis. Differential detection of pancreatic ductal dilatation indicates, a need for detailed examination with CT, ERCP, EUS or IDUS, to provide a diagnosis after detection of pancreatic ductal dilatation. IPMT develops slowly and benign IPMT may be followed up without surgery. Differentiation between benign and malignant tumors is important for appropriate treatment. MRCP is exellent in detecting dilated pancreatic ducts, and EUS in the mural nodule. These imaging modalities are were useful for decisions on treatment strategies. |
