由于B超和CT扫描在腹部的广泛应用,胰腺囊性病变,尤其是胰腺炎或钝伤后假性囊肿的显示率有所增多。Robson和Moynihan(1903)将胰腺囊肿分为三类:潴留性、先天性和增生性。增生性囊肿包括良性的囊腺瘤和恶性的囊腺癌。囊腺瘤约为胰腺非恶性囊性病变的10％,而囊腺癌则占原发性胰 Due to the extensive use of B-scan and CT scan in the abdomen, the display rate of pancreatic cystic lesions, especially pancreatitis or pseudocyst after dullness, has increased. Robson and Moynihan (1903) classified pancreatic cysts into three categories: residual, congenital, and proliferative. Proliferative cysts include benign cystadenoma and malignant cystadenocarcinoma. Cystic adenomas account for approximately 10% of non-malignant cystic lesions of the pancreas, while cystadenocarcinomas account for primary pancreatic tumors.
