摘　　要：目的 探讨肺硬化性血管瘤的X线、CT、PET-CT表现及其诊断价值.方法 回顾性分析17例经手术病理证实的肺硬化性血管瘤的影像学资料.结果 左肺发病10例,右肺7例,单发病灶16例,多发1例2个病灶 除2例出现分叶外,其余病灶均表现为边界清楚的类圆形结节影.12例行CT检查,1例见多发不规则钙化,平扫时硬化性血管瘤呈均匀等密度,9例增强扫描后病变呈明显强化 1例在PET-CT上未见显影剂浓聚.结论 胸片有助于硬化性血管瘤的检出,但定性诊断困难,CT平扫及增强扫描对其诊断价值较高.PET-CT可以判断硬化性血管瘤的良、恶性,但其检查费用昂贵.Objective To investigate X--ray film,CT and PET--CT features of pulmonary sclerosing hemangioma and it＇s diagnostic value. Methods Imaging data and clinical informatlons of 17 patients with pulmonary sclerosing hemangioma confirmed by pathology were retrospective reviewed. Results The lesions involved left lung in 10 cases and right lung in 7,16 cases were single and 1 case was multiple. The lesions showed lobule in 2 cases and like--round nodi with clearly border in 15 cases. 12 cases underwent CT examinations, the lesions showed multiple irregular calcification in one case, at plain CT scan, sclerosing hemangiomas showed uniformly isodensity,after injection of contrast medium,the lesions showed obviously enhancement in 9 cases. 1 case underwent PET-- CT examination and there was no abnormality. Conclusion Plain chest X--ray can be hepful in detection of sclerosing hemangioma, but qualitative diagnosis is difficult;CT scan is of important diagnostic value, while PET--CT differentiating benign sclerosing hemangioma from malignant one, but it is very expensive.
