摘要
目的探讨原发性肺肉瘤的CT表现及诊断价值。方法回顾性分析3例经病理证实的原发性肺肉瘤的临床和CT检查资料。结果3例均为男性,年龄分别为16、44、71岁。属平滑肌肉瘤、横纹肌肉瘤和滑膜肉瘤各1例,其中中央型1例,周围型2例。中央型表现为肺门结节,支气管壁增厚,管腔狭窄及阻塞性改变。周围型表现为肺内巨大肿块伴点状、斑片状钙化,增强明显强化,边界清楚,密度不均,无纵隔及肺门淋巴结转移。结论原发性肺肉瘤中央型CT表现难与肺癌鉴别,周围型有一定的特征性,有助于临床诊断。
Objective To evaluate the CT findings and diagnostic value of primary sarcomaof lung.Methods3 cases of primary sarcoma of lung proved by biopsy were analyzedretrospectively.ResultsAll 3 patients were male with age of 16、44 and 71 yearsold,respectively.There were leiomyosarcoma(n=1), rhabdomyosarcoma(n=1) and synovial sarcoma(n=1).In CT scanning,there were central type (n=1) and peripheral type (n=2).Central typedisplayed hilum of lung nodule,thickened wall of the bronchus,obstructed or narrow bronchusand obstructive penumonia.Peripheral type without lymph node metastasis in hilum of lung ormediastina, showed giant mass in lung,a sharply demarcated、containing calcification,obviousenhancement and inhomogeneous density.ConclusionIt is difficult to indentify the centraltype of primary sarcoma of lung from bronchogenic carcinoma in CT scanning. Peripheral typehas a relatively special features,which is helpful for clinical diagnosis.
