摘要
目的 :提高单发肝转移瘤的诊断水平 ,探讨CT检查价值。方法 :从肝脏转移瘤手术追踪病例中找出术前CT检查 2 0例 ,进行CT回顾性分析 ,并对单发肝转移瘤在肝内分布、密度、CT增强表现、临床肝脏检查情况及原发灶同时显示予以分析。结果 :2 0例单发肝转移瘤中 ,11例 (5 5 % )病灶位于肝脏边缘的肝实质内 ,14例 (70 % )病灶比肝实质密度低 ,甲胎蛋白 (AFP)测定 :12例 (6 0 % )AFP <2 0 μg/l,CT检查同时发现原发肿瘤 5例 ,术前误诊 6例 (33.3% )。结论 :单发肝内转移瘤是高误诊的主要原因 ,注意分析临床症状、肿瘤在CT的分布特点、密度、增强CT的特性及原发肿瘤的部位 ,加强寻找原发灶 。
Objective: To study the value of CT examination to improve the diagnostic level of single hepatic metastses. methods: We retrospected preoperation CT examination of 20 patients who were diagnosed by operation and analysed the distribution and density of single hepatic metastases in liver, manifest of enhanced CT, clincal examination of liver and the manifest of primary focus. Results: In 20 cases, focuses of 11 cases (55%) located in the parenchyma of edge of liver, the density of 14(70%) focuses lower than liver parenchyma, AFP measurement: 12 cases (60%)<20μg/l, primary focuses were found simultaneously in 5 cases by CT examination. 6 case (33.3%) were misdiagnosised befor operation. Conclusion: Single hepatic metastases is the main cause of high ration misdiagnosis. The clincal signs, the distribution character and density of tumor in CT, the character of enhanced CT and the location of primary tumor should be analysed synthetically.
