肺硬化性血管瘤CT表现与临床病理对照分析

目的:分析肺硬化性血管瘤(SHL)的CT表现特点,以及与临床病理之间的关系,提高术前诊断水平。方法:回顾性分析经手术病理证实的7例SHL患者的CT图像资料,并与手术病理相对照,探讨该病的CT诊断特点。结果:6例CT表现为肺内孤立性软组织肿块或结节、密度均匀,病变轮廓清楚、边缘光滑者4例,边缘浅分叶2例;1例表现为双肺内多个类圆形结节;1例可见小的钙化。CT增强扫描病灶明显强化,4例均匀强化,3例不均匀强化。CT表现与病理的关系是增强扫描后病灶强化明显与不明显的区域分别对应于其血管瘤成分与实性区。结论:SHL的临床症状和CT平扫无明确特征表现,CT增强扫描对病变的诊断和鉴别诊断具有重要的价值。

Sclerosing hemangioma of lung: comparative study on CT findings and pathology

Objective： To analyze the CT findings characteristics of sclerosing hemangioma of lung （SHL） and their relationship with pathology, in order to improve the accurate rate of its diagnosis before surgery. Methods： CT findings in 7 cases pathologically proved sclerosing hemangiomas were retrospectively analyzed in comparison with pathology. Results：CT scanning showed 6 cases appearing soft tissue solitary mass or round nodular with homogeneous density, and with smooth margin in 4 cases and superficial lobulation in 2 cases; 1 case showed many round nodules in double lung; 1 case with slight calcification was found, 4 cases were homogeneous enhancement and 3 cases were heterogeneous enhancement on contrast-enhanced scan. The obviously strengthening regional and the no obvious areas on contrast-enhanced scan corresponded with angiomatous and solid areas respectively on pathology. Conclusion： Clinical symptoms and unenhanced CT scan of SHL have not remarkable characteristics, contrast-enhanced CT scan have important evaluation in diagnosis and differential diagnosis of SHL.
