| ［摘要］ 目的 分析肺硬化性血管瘤（PSH）的CT特征及病理基础，以提高对该病的认识。方法 回顾性分析9例经病理证实的PSH的临床和CT检查资料。结果 PSH多见于40岁女性；表现为直径1～3 cm,境界清晰的圆形、类圆形肺内结节或肿块；CT平扫密度均匀，有时见点片状钙化；CT增强见均匀或不均匀强化，且有延迟强化；相对特殊征象:空气新月征、贴边血管征、晕征等。结论 PSH的CT表现具有一定的特征性，有利于其诊断与鉴别诊断。 |

| ［Abstract］ Objective To improve knowledge of pulmonary sclerosing hemangioma（PSH）and investigate the CT findings correlated with it′s pathologic changes.Methods The clinical date and CT date in 9 patients with PSH proved by pathology were retrospectively analyzed.Results The disease mainly occurred in female patients 40 years old;on CT, the lesion presented as 1～3 cm in diameter well-defined, round and oval shaped mass or nodule；a homogeneous soft-tissue mass on unenhanced CT,calcification was found in some lesions;homogeneous or heterogeneous enhancement after contrast administration;on delayed phase scans, some of them demonstrated late enhancement；the seemingly characteristics：air-trapping zone, vessels at its periphery.Conclusion Although the final diagnosis of PSH depends on pathology, CT is helpful to its diagnosis and differential diagnosis. |
