目的：分析肺硬化血管瘤的影像学特征。方法回顾性分析20例经手术和病理检查确诊的肺硬化血管瘤患者的影像学表现。结果20例患者均为单发病灶，且病灶直径为10～75 mm（平均直径为45 mm），其中病灶为圆形的有12例，椭圆形的有8例，所有患者病灶密度均匀，且未见坏死灶或者是钙化影，同时均未见毛刺。7例行增强CT扫描均可见血管特征；8例行PET／CT扫描，诊断准确率为41．1％，肺硬化血管瘤对FDC的摄取无特异性。结论对肺硬化血管瘤患者行CT平扫之后再行CT增强扫描，能有效提高诊断率。

Objective To investigate the imaging characteristics of pulmonary sclerosing heman-gioma ( PSH) .Methods The imaging characteristics of 20 cases of PSH patients diagnosed by operation and pathological section were retrospectively an-alyzed.Results All the 20 patients were proved to be with single lesion,and the diameter of the lesion was 10-75 mm( mean 45 mm) .The lesions of 12 cases were found to be round,while those of the other 8 cases were elliptic.All the lesions were homoge-neous in density,without focal necrosis or calcification lesions,and no burr were found.The vascular characteristics of the 7 pa-tients diagnosed with CT contrast enhanced scan were visible,which was helpful for the diagnosis.The diagnosis accuracy rate of the 8 patients diagnosed with PET/CT scan was 41.1%,no specific uptake of FDC were detected.Conclusion Combined appli-cation of CT noncontrast enhanced scan and CT contrast enhanced scan can effectively improve the diagnosis accuracy,and PET/CT scan can improve diagnosis accuracy.
