摘　　要：目的 探讨肺硬化性血管瘤（PSH）的CT特点，提高对本病的认识。方法 回顾性分析24例经手术病理证实的PSH的CT特征。所有病例均行胸部CT平扫与动态增强扫描。结果 病灶位于右肺者14例，左肺10例；最大径为0．8～10cm，平均3.08cm；有3例位于肺门区，其余均位于肺外围（87．5％）；20个病灶类圆形，4例有浅分叶，87．5％的病灶（21例）边缘光滑，45.8％（11例）的病灶有钙化，增强以后均有比较明显的强化，平均CT值净增（46．62±9．47）HU，有2例较大病灶内部尚可见到粗大扭曲的血管影。结论 PSH除具备一般肺内良性肿瘤的特点外，有明显强化以及容易出现钙化是其特征性改变。Obiective To evaluate CT characteristics of pulmonary sclerosing hemangioma （ PSH ） so that to improve the knowledge of this disease . Methods CT characteristics of PSH pathologically verified were retrospectively analysed . Conventional scan and contrast - enhanced scan were performed in all the patients. Results 14 lesions were in right lung, while 10 were in left, Diameters of these lesions ranged from 0.8 to 10 cm, and the average diameter was 3.08 cm. 3 lesions were located in hilum of lung, while the rest（ 87.5% ） were located in peripheral lung tissue. 20 lesions were oval, and 4 were lobulated in morphology. 21 lesions were smooth in edge. 45.8% of the cases had calcification. All the lesions enhanced obviously on contrast -enhanced scan, and average CT value of（46.62 ± 9.47） HU was increased. The dilated and distorted blood vessels could be detected in 2 large lesions. Conclusion On the basis of general benign tumor features, obvious enhancement and calcification are the characteristics of PSH on CT.
