作者报道4例胰腺囊性肿瘤和1例少见的实性乳头状上皮瘤的US、CT、血管造影以及病理检查。均为女性,年龄49～54岁。超声检查,例1～4显示为囊性肿瘤,例5为实性肿瘤,中心有囊性变。CT 增强例1～4表现为囊性肿瘤,例1、2囊壁有钙化,例3,4囊壁有实性部分突入囊内或囊壁不规则并有腹膜播散或肝转移。例5监示中心有低密度区,增强显示边缘不规则。血管造影例1、5有肿瘤染色。例2无阳性表现,例3、4、5有脾动脉抬高。病理组织学检查,例1为小囊性腺瘤。例2、3为粘蛋白囊腺瘤。例4未见恶性表现,但3个月后肝转移死亡。例5为实性乳头状上皮瘤。作者指出,胰腺原发肿瘤90%为胰管腺癌,
The authors reported US, CT, angiography, and pathological examination of 4 cases of pancreatic cystic tumor and 1 case of solid papillary epithelium. All women, aged 49 to 54 years old. Ultrasonography showed cases 1 to 4 as cystic tumors, and case 5 as solid tumors with central cystic changes. The CT enhancements 1 to 4 showed cystic tumors, calcifications of the walls of cases 1 and 2, and cases 3 and 4 of the wall had solid parts protruding into the cyst or irregularities of the wall and peritoneal dissemination or liver metastases. Example 5 shows that the monitoring center has a low density area and enhances the display edge irregularity. Angiographic examples 1 and 5 have tumor staining. Example 2 showed no positive performance, and cases 3, 4, and 5 had splenic artery elevation. Histopathological examination, Example 1 is a small cystic adenoma. Examples 2 and 3 are mucin cystadenoma. There was no malignant appearance in Example 4, but liver metastases died after 3 months. Example 5 is solid papillary epithelioma. The authors pointed out that 90% of primary pancreatic tumors are pancreatic ductal adenocarcinomas.
