目的分析肺硬化性血管瘤的多层螺旋CT影像表现,探讨多层螺旋CT在肺硬化性血管瘤诊断的临床价值。方法回顾性分析经临床病理证实的36例肺硬化性血管瘤的多层螺旋CT影像资料并进行总结。36例均行CT平扫及增强检查。结果 36例肺硬化性血管瘤病例中,全部为孤立性病灶;病灶在两肺内无明显好发部位。平扫时24例病灶密度较均匀,6例病灶内见细沙样钙化;9例可见“空气新月征”;增强扫描后,其中12例病灶明显均匀强化;21例病灶呈明显不均匀强化;3例病灶增强扫描未见明显强化。6例可见“贴边血管征”。结论多层螺旋CT及其图像后处理技术能更全面地显示肺硬化性血管瘤的形态特征,对该病的诊断和治疗具有重要的指导意义。
Objective To analyze the multi-slice spiral CT findings of pulmonary sclerosing hemangioma and investigate the clinical value of multi-slice spiral CT in the diagnosis of pulmonary sclerosing hemangiomas. Methods Retrospective analysis of 36 cases of pulmonary sclerosing hemangiomas confirmed by clinical pathology was performed and the data were summarized. 36 cases underwent CT scan and enhanced examination. Results 36 cases of pulmonary sclerosing hemangioma cases, all isolated solitary lesions; lesions in the two lungs no significant sites. In the plain scan, the density of 24 lesions was more uniform, and fine sand-like calcification was seen in 6 lesions. In 9 cases, “air crescent sign” was seen; in 12 cases, the lesions were markedly and uniformly enhanced after enhanced scanning; Uniform enhancement; 3 cases enhanced enhancement of the lesion showed no significant enhancement. 6 cases can be seen “Vascular edge ”. Conclusion Multi-slice spiral CT and its image post-processing technique can display the morphological characteristics of pulmonary sclerosing hemangiomas more comprehensively, which has important guiding significance for the diagnosis and treatment of the disease.
