摘　　要：目的 探讨肺硬化性血管瘤（PSH）的CT表现，旨在提高对PSH影像学表现的认识。方法 回顾分析21例经手术及病理证实的PSH的CT资料，将CT表现与病理学对照。结果 （1）PSH多见于30～50岁女性；（2）表现为直径1～5cm，境界清晰的圆形、类圆形肺内结节或肿块；（3）CT平扫密度均匀，有时见粗大点片状钙化，2例较大病灶内（≥5cm）可见囊性变；（4）CT增强见均匀或不均匀强化，且有延迟强化；（5）相对特殊征象：空气新月征4例、贴边血管征5例、尾征7例。结论 PSH好发于中青年女性，CT显示的空气新月征、贴边血管征、尾征具有相对特征性，有助于术前诊断。Objective To study the CT features of pulmonary sclerosing hemangioma（ PSH ） , so that to improve the imaging diagnostic abilities. Methods 21 cases pathologically proven PSH were included in this retrospective article. Imaging features were compared with pathological results. Results （ 1 ） The disease mainly occurred in female patients between 30 - 50 years old; （2） On CT, the lesion presented as well -defined, round and oval shaped mass or nodule; （3） A homogeneous soft - tissue mass on unenhaneed CT; calcification was found in some lesions; in 2 cases, cystic- like area was found within large tumors（≥5cm） ; （4）Homogeneous or heterogeneous enhancement after contrast administration ; on delayed phase scans, some of them demonstrated late enhancement ; （5） The seemingly characteristic air - trapping zone, vessels at its periphery and a tail sign were found in 4, 5, 7 cases respectively. Conclusion PSH should be considered in young and middle - aged female patients, with the characteristic presence of air - trapping zone, vessels at its periphery and a tail sign within images （especially on CT）. And the disease can be preoperatively diagnosed combined with the clinical features with above the aforementioned features.
