摘 要: | 目的 探讨胰腺囊腺瘤与囊腺癌的CT影像学特征.方法 回顾性分析经过病理证实的21例浆液性囊腺瘤、12例黏液性囊腺瘤、6例黏液性囊腺癌的CT影像学资料,分析肿瘤部位、单(多)囊、最大囊直径、囊壁特征、囊内分隔、肿瘤边界、肿瘤与胰管关系等影像学征象.结果 21例浆液性囊腺瘤中17例位于胰头颈部,5例位于胰体尾部,其中1例为多发;均为多囊,平均最大囊直径为1.8 cm;4例囊壁或分隔有钙化,7例分隔可见软组织成分;10例胰管轻度增宽.12例黏液性囊腺瘤中6例位于胰头颈部,6例位于胰体尾部;4例为多囊,平均最大囊直径为4.5 cm;1例分隔可见钙化,6例囊壁可见软组织成分;2例胰管扩张,3例胰管轻度增宽.6例黏液性囊腺癌中5例位于胰体尾部,1例位于胰头颈部;4例为多囊,平均最大囊直径为5.1 cm;1例分隔可见钙化,5例囊壁可见软组织成分;1例胰管扩张,1例胰管轻度增宽.所有病灶与胰管均不相通,增强后病灶软组织成分及分隔均有不同程度强化.结论 胰腺囊腺瘤与囊腺癌的CT表现具有一定的特征性,但对于少数不典型表现病例,诊断仍存在困难.

Abstract: | Objective To investigate the CT radiological features of pancreatic cystadenomas and cystadenocarcinomas. Methods The CT scans from 39 patients with pathologically proven cystic pancreatic tumors (21 cases of serous cystadenomas, 12 cases of mucinous cystadenomas, and 6 cases of mucinous cystadenocarcinomas) were retrospectively analyzed. Tumor location, the number of cyst (polycystic or not) , diameter of the largest cyst, features of the cyst wall, partition within cyst, border of tumor, and the relationship between tumors and pancreatic duct were recorded. Results In 21 patients with serous cystadenomas, tumors were located at the pancreatic head and neck areas in 17 cases, at the pancreatic body and tail areas in 5 cases, and 1 case was multiple. All 21 cases were polycystic; the median diameter of the largest cyst was 1.77 cm; calcification was seen in cyst wall or partition in 4 cases and soft tissue was seen in 7 cases; mild pancreatic duct dilatation was found in 10 cases. In 12 patients with mucinous cystadenomas, tumors were located at the pancreatic head and neck areas in 6 cases, at the pancreatic body and tail areas in6 cases; 4 cases were polycystic; the median diameter of the largest cyst was 4.88cm; calcification was seen in 1 case and soft tissue was seen in 6 cases; pancreatic duct dilatation was found in 2 cases and mild duct dilatation was found in 3 cases. In 6 patients with mucinous cystadenocarcinomas, tumors were located at the pancreatic body and tail areas in 5 cases, tumor was located at the pancreatic head and neck areas in 1 case; 4 cases were polycystic; the median diameter of the largest cyst was 5.09 cm; calcification was seen in 1 case and soft tissue was seen in 5 cases; duct dilatation was found in 1 case. In all cases, there was no pancreatic duct communication. After enhancement, the soft tissue and partition of lesion was enhanced to gome extent. Conclusions There are CT radiological features of pancreatic cystadenomas and cystadenocarcinomas. However, there are still some atypical CT appearances that may challenge the diagnosis. |
