Research on CT Differential Diagnosis of Benign and Malignant in Pancreatic Cystic Lesions

Purpose:The study uses spiral CT system to analyze and explore the performance and features of pancreatic cystic lesions imaging for the differential diagnosis.Materials and Methods:The authors analyze 33 cases confirmed by surgery and pathology of pancreatic cystic lesions and enhanced CT scan features of the site of the incidence,size,shape and internal cystic lesions and the surrounding enhanced features.All these used as the basis of the differential diagnosis,also patients′ age,sex and clinical manifestations are considered.Results:In the study group,there are 1case of congenital cyst,26 cases of pseudocyst,three cases of serous cystadenoma,2 cases of mucinous cystadenoma,one cases of pancreatic cystic degeneration.Pseudocyst is thin-walled and no enhancement while benign cystadenoma is thick-walled,smooth,and separation of its mural nodules can be seen.Wall and mural nodules are mild to moderate enhancement,and malignant wall is uneven,moderately enhanced and fuzzy boundaries.Conclusion:Pancreatic pseudocyst is easier to cause cystic lesion and cystic tumor with the performance characteristics of CT.Using CT scan can make more accurate judgments on benign and malignant cystic lesions.
