肺原发性软骨瘤12例多层螺旋CT征象及病理分析

MSCT findings and pathological analysis of 12 cases of primary chondroma of the lung

目的观察肺原发性软骨瘤的多层螺旋CT(MSCT)表现,并分析其病理结构特点。方法 2013年1月—2017年8月成都市第五人民医院诊治经病理证实的原发性肺软骨瘤患者12例并对其MSCT表现进行回顾性分析。结果原发性肺软骨瘤均位于肺周围带12例(100.0%);病灶位于右肺8例(66.7%),病灶多呈单发边缘光滑的无分叶结节或软组织肿块影,病灶内多出现斑点状、小斑片状及蛋壳状钙化8例(66.7%),增强CT为轻—中度强化,CT值(28.4±11.8)Hu。结论肺原发性软骨瘤以单发、外周带居多,男性高发,病灶内伴有小片状、斑点状钙化为其特异性征象,其病理学表现有其特征性,最终确诊依赖病理学诊断。

Objective To observe the MSCT manifestations of primary chondroma of the lung and analyze its pathological features.Methods From January 2013 to August 2017,12 patients with pathologically proved primary pulmonary chondroma were treated in Chengdu Fifth People's Hospital and their MSCT findings were retrospectively analyzed.Results Primary lung chondromas were located in the periphery of the lung in 12 cases(100.0%);the lesions were located in the right lung in 8 cases(66.7%),and the lesions were mostly single-edge smooth-leaved no-lobed nodules or soft tissue masses.There were 8 cases(66.7%)with spotted,small patchy and eggshell calcification.The enhanced CT was light-moderately enhanced with CT value(28.4±11.8)Hu.Conclusion Primary chondroma of the lung is predominantly solitary and peripheral,with a high incidence in males.The lesions are accompanied by small patches and punctate calcification.Its pathological manifestations have their own characteristics.The final diagnosis depends on pathological diagnosis.
