粘液性胰腺癌在组织病理学上并非单一的肿瘤,它包括粘液腺癌,乳头腺癌及囊泡腺癌。肿瘤发生在主副胰管或比较粗的分枝的胰管上皮,胰癌沿胰管表面增殖,很少向胰实质及胰外浸润,切除率高,预后较好。作者分析了5例粘液性胰腺癌的CT图象,并与慢性胰腺炎进行对照。粘液性胰腺癌均可见主胰管扩张,3例呈弥漫性扩张,2例只胰头部胰管限局性扩张。主胰管壁不整3例,平滑2例。主胰管平均直径16±8.3mm,最大28mm,最小7mm。5例中3例有十二指肠壁内胰管扩张。肿瘤位于主胰管者2例中1例于扩张的主胰管内腔
Mucinous pancreatic cancer is not a single histopathological tumor. It includes mucinous adenocarcinoma, papillary adenocarcinoma, and cystic adenocarcinoma. Tumors occur in the main pancreatic duct or pancreatic duct epithelium with relatively thick branches. Pancreatic cancer proliferates along the surface of the pancreatic duct. It rarely infiltrates into the pancreatic parenchyma and outside the pancreas. The resection rate is high and the prognosis is good. The authors analyzed CT images of 5 cases of mucinous pancreatic cancer and compared them with chronic pancreatitis. Mucinous pancreatic cancer can be seen in the main pancreatic duct dilatation, 3 cases showed diffuse expansion, 2 cases of pancreatic head and pancreatic duct only limited expansion. The main pancreatic duct wall was incomplete in 3 cases and smooth in 2 cases. The average pancreatic duct diameter 16 ± 8.3mm, the largest 28mm, the smallest 7mm. Three of the 5 cases had duodenal pancreatic duct dilation. The tumor is located in the main pancreatic duct in 2 patients with main pancreatic duct
