摘 要: | 目的:探讨肺硬化性血管瘤(PSH)的CT表现,旨在提高对该病的认识及诊断水平。方法:回顾性分析经手术病理证实的t0例PSH患者,其中男1例,女9例,年龄47~68岁,平均57.6岁。10例均行胸部CT检查,其中1例仅行CT平扫,9例行CT平扫及增强扫描。结果:病灶部位:右肺3例,其中上叶1例,中叶2例;左肺7例,其中上叶4例,下叶3例。病灶形态:10例均为圆形、类圆形肺内肿块或结节,境界清晰.分叶不明显(4例有浅分叶)、无毛刺、胸膜牵拉凹陷、卫星病灶及血管集束征等征象。病灶大小:均为单发,最大径1.7~5.1cm,其中〈3cm者6例。病灶密度:CT平扫4例密度较均匀,6例见斑片状稍低密度区,4例见点状或粗大点片状钙化;CT增强均匀强化3例,不均匀强化6例,9例中7僻呈延迟强化。特征性的征象:空气新月征1例、贴边血管征10例、尾征3例、晕征7例。结论:空气新月征、贴边血管征、尾征、晕征等CT征象具有一定的特征性。有助于PsH的术前诊断。

Abstract: | Objective:To study both unenhanced and dynamic enhanced CT features of pulmonary sclerosing hemangi oma (PSH),in order to improve the understanding and diagnostic level of this diesease. Methods: 10 cases (9 females and 1 male) with surgical and pathological proven PSH were retrospectively studied. The age of all patients were between 47-68 years (mean 57.6). All of them undwent chest CT scan,9 of them underwent both pre-contrast and post-contrast scan, the other one only had plain CT scan. Results:The location of lesion:3 of 10 cases were in right lung,including 1 in upper lobe and 2 in middle tobe;7 cases were in left lung,including 4 in upper lobe and 3 in lower lobe. All lesions presented as well-de fined round and oval shaped mass or nodule,and without spicules, pleural indentation, deep lobulation, satellite lesions or vessel convergence. However,there were 4 cases with scallop-shaped contour. All cases presented with single lesion with a mean long axis diameters ranged 1. 745. lcm,6 of which were less than 3cm. On plain CT,4 of the 10 cases presented ho mogeneious desity. In 4 of these 10 cases the lesion contained dotted or coarse granular and patchy calcification. Post-con- trast scanning showed homogeneous enhancement in 3 cases,and patchy heterogeneous enhancement in 6 cases. In these 10 cases,7 had delayed enhancement. About the relative special CT finding in this study, 1 case had air meniscus sign, I0 cases had welt vessel signs, 3 cases had tail signs and 7 cases had halo signs. Conclusion: The characteristic findings of PSH in CT exam were air meniscus sign,welt vessel signs,tail signs and halo signs. The dynamic enhanced CT is helpful in diagnosis of PSH before operation. |
