肝尾状叶乳头突的超声图像观察及其意义

SONOGRAPHIC IMAGE OF PAPILLARY PROCESS IN CAUDATE LOBE OF LIVER

目的 :探讨肝尾状叶乳头突 (以下简称乳头突 )的超声图像表现并进行鉴别诊断 ;方法 :对 650例体检者行中上腹超声探查 ,显示乳头突者仔细观察 ,并记录其径线大小 ;结果 :有 64例显示乳头突图像 ,占所检人数 1 0 % ,横断时均为孤立的卵圆形结构 ,纵断时约 1 / 3亦表现为孤立的结构 ,约 2 / 3可见乳头突与尾状叶主体之间连接部 ,部分人乳头突下缘达胰颈部 ;结论 :超声医师应熟悉乳头突超声特征 ,以免误诊为腹腔肿大淋巴结或胰颈部占位。

Objective: To evaluate the sonographic appearance of the papillary process in the caudate lobe of liver and its identification and diagnosis. Methods: 650 subjects were studied prospectively by ultrasonography. The subjects with the papillary process were closely studied and the diameter of the papillary process was recorded.Results: The papillary process was found in 64 subjects(10%). The papillary process appeared to be isolated oval structure on transverse sonograms. The papillary process appeared to be isolated structure on longitudinal sonograms in one third of the subjects. The connection of the papillary process and the caudate lobe was seen in about two thirds of the subjects. The low part of the papillary process was close to the portal vein and pancreatic isthmus. Conclusions: The sonologist (sonographer) are supposed to be familiar with the sonographic feature of the papillary process in case he or she diagnoses it as tumescence of abdominal lymph or the masses of pancreatic isthmus.
