目的探讨CT对肺透明细胞瘤的诊断价值。方法回顾性分析2例肺透明细胞瘤的临床资料、CT表现,并结合文献分析该病的病理、CT诊断及鉴别诊断。结果 1例为左肺下叶外基底段结节,密度均匀,增强扫描均匀明显强化;另1例为左肺上叶舌段类圆形肿块,密度不均匀,内部见钙化灶,增强扫描不均匀轻~中度强化。结论 CT检查是目前诊断肺透明细胞瘤主要的影像检查方法,其表现具有一定特征,多为圆形、边界光滑的实性结节或肿块,增强扫描均匀明显强化,当肿块内出现钙化时则为轻~中度强化。确诊需依靠病理、免疫组织化学。
Objective To investigate the value of CT in the diagnosis of lung clear cell tumor. Methods The clinical data and CT findings of 2 cases of lung clear cell tumor were retrospectively analyzed. The pathological, CT diagnosis and differential diagnosis of the disease were analyzed based on the literature. Results In 1 case, the nodules of the left lower lobe outside the basal segment had uniform density and enhanced contrast enhancement. The other 1 case was a round lump of lingual segment of the left upper lobe with uneven density, internal calcification, enhanced scanning Even light ~ moderate enhancement. Conclusions CT examination is the main imaging method for the diagnosis of pulmonary clear cell tumor. Its performance has some characteristics, mostly round, solid nodules or lumps with smooth border. The enhanced scan is even and obviously enhanced. When calcification occurs in the mass Light ~ moderate enhancement. Diagnosis depends on the pathology, immunohistochemistry.
