46例隐匿性肺癌并颅内单发转移回顾性分析

目的探讨单发脑转移瘤患者胸部CT检查的意义。方法回顾性分析46例隐匿性肺癌引起颅内单发转移患者的胸部影像等表现。结果46例患者胸部CT均有阳性诊断结果,其中肺尖癌11例(23.9%),心后区、脊柱旁及奇静脉窝癌15例(32.6%),后肋膈角区癌18例(39.1%),中间支气管周围癌2例(4.4%);平片只有12例(26.1%)有异常表现,无1例能确诊。结论对于隐匿性肺癌,CT检查能明确诊断;对于颅内单发肿瘤而临床高度怀疑转移瘤患者,应行胸部CT检查。

Retrospective Analysis on 46 Cases of Occult Lung Cancer with Single Metastasic Encephaloma

Objective To investigate the significance of chest CT examination in single metastasic encephaloma.Methods 46 cases chest X-ray and CT examinations of occult lung cancer with single metastatic encephaloma were analyzed retrospectively.Results All 46 cases had positive image results in CT,including 11 cases(23.9%) with apex pulmonis cancer,15 cases(32.6%) with postcardial?paravertebral and azygos vein fossa cancer;18 cases(39.1%) with retroastophrenic angle cancer,and 2 cases(4.4%) with peribrochial cancer.But only 12 cases(26.1%) had abnormal image manifestation in X-ray,and none of them was helpful for diagnosis-making.Conclusion Chest CT examinations is useful for diagnosis of occult lung cancer.For a patient who is highly suspected to have metastatic encephaloma,if the chest X-ray manifestation is negative,chest CT may be a useful examination for the diagnosis-making.
