目的 探讨跨裂生长特征对于中 央型硬化性肺泡细胞瘤的价值研究。方法 回顾性分析经手术病理证实的10例跨裂生 长的肺门旁占位，分析该特性在不同疾病 中的影像表现。结果 10例结节中，7例为 中央型硬化性肺泡细胞瘤(女性6例，男性 1例，空气新月征3例，晕征4例)。1例腺 癌，1例为结核球,1例为错构瘤，10例结 节均有强化。结论 跨裂生长对于诊断中 央型硬化性肺泡细胞瘤一定的特异性，有 助于其正确诊断。

Objective To investigate the diagnosis value of the cross crack growth characteristics for pulmonary sclerosing pneumocytoma (PSP) of central type. Methods A retrospective analysis of 10 cases of pathologically confirmed cross crack growth of parahilar occupying, analysis of the characteristics in different disease manifestations of. Results Of the 10 cases, there were 7 cases of PSP of central type (female in 6 cases, male in 1 case, air crescent sign in 3 cases, halo sign in 4 cases). 1 case of adenocarcinoma, 1 case of tuberculoma, 1 case of hamartoma, 10 cases of nodular enhanced. Conclusion The cross section growth characteristic has a certain specificity in PSP of central type, which may help for definite diagnosis.
