摘要
目的评价CT和低张十二指肠造影(HD)诊断和鉴别诊断十二指肠腺瘤的价值。资料与方法回顾分析6例十二指肠腺瘤的CT和HD表现,对照手术病理所见,对CT、HD在显示病变、定性诊断与鉴别诊断的作用进行评价。结果HD表现为充盈缺损,其中5例边缘光滑,1例边缘欠光滑,3例呈椭圆形与肠道纵轴平行,2例轻度分叶,1例显示蒂部,2例肿瘤可移动,周围黏膜正常,管壁柔软。主要CT征象为腔内肿块,密度均匀,边缘光滑,轻～中度均匀强化。2例壶腹区腺瘤显示胆系轻～中度扩张。结论CT可显示腔内病变及腔外改变。HD观察腔内异常,尤其显示带蒂腺瘤蒂部及位置改变优于CT,且具有诊断特征。二者结合有助于提高诊断正确性。
Objective To assess the value of CT and hypotonic duodenography（HD） in diagnosing the duodenal adenomas. Materials and Methods CT and HD signs of 6cases of duodenal adenomas were reviewed and compared with the pathologic findings. The diagnosis and differential diagnosis values of CT and HD were evaluated. Results At HD ,the filling defects were demonstrated. 5 lesions had smooth margin and 1 lesion had slightly irregular margin. 3 lesions with elliptic shape had their longitudinal axis paralleled to that of the intestine. 2 of 3 lesions slightly lobulated, 1 lesion with pedicle and 2 lesions movable. In addition,peripheral mucosa was normal. Intestinal wall was soft. The main CT signs included intraluminal mass with homogeneous entity, sharp margin and light to moderate enhancement. 2 cases of the periampullary adenomas showed light to moderate dilation of bile ducts. Conclusion CT can display both intraluminal and extraluminal lesions. HD excels CT in observing intraluminal abnormalities, especially in demonstrating the pedicels and the movement of the adenomas which are regarded as the diagnosable characters. Combining CT with HD will improve the diagnosis of duodenal adenomas.
