摘要
目的 提高脑干转移瘤的 CT诊断及鉴别诊断。方法 经 CT诊断及临床确认原发灶的脑干转移瘤 8例 ,男 7例 ,女 1例 ,年龄 5 0~ 71岁 ,平均 6 0 .5岁。采用 2 0 6 0 - Q型 CT机及 Picker- 2 0 0 0 S螺旋 CT机扫描 ,分析其脑干转移瘤的临床 CT表现特点。结果 7例脑干转移瘤呈低或略低密度影 ,1例单一结节为略高密度影 ,伴随脑内其他部位多发转移 2例 ,3例增强扫描呈环形强化 ,较度水肿 6例 ,无水肿 2例 ,环池有不同程度受压移位、变形 ,以及局限性闭塞或增宽。结论 认识脑干转移瘤的 CT表现特点有助于其鉴别诊断 ,尤其是脑干缺血性梗死。
Objective To improve the CT diagnosis and differential diagnosis of brain stem metastasis. Methods 8 cases(male 7 and female 1,ranged from 50~71 years in age,mean 60.5 years) of brain stem metastasis were diagnosised finally by CT and clinic. All cases were scanned by 2060 Q and Picker 2000S spiral CT. The CT features of these cases were analysed. Results Among 8 cases,there were low or low slightly density as in 7 cases, single high slightly density tubercle as in 1 case, following these,there were multiple neoplasm metastasis of brain other sites in 2 cases, annular shape enhancement in 3 cases after contrast CT scanning, peripheral edema lightly as in 6 cases and no in 2 cases, suprasellar region, ambiens cisterna and corpora quadrigemina were compressed, transposited and distorted differentlly,and obturated or widened locally. Conclusions To know the CT features are helpful to differential diagnosis of brain stem metastasis,especially to infarction and hemorrhage of brain stem.
