中文摘要:目的:探讨肺硬化性血管瘤(pulmonary sclerosing hemangioma,PSH)的CT影像学表现。方法:回顾分析经手术及病理证实的18例肺硬化性血管瘤患者的CT影像学资料。所有患者均行多层螺旋CT增强检查,其中8例先行CT平扫检查。结果:所有病例的PSH均为单发病灶,直径为1.4~7.6 cm,平均3.5 cm;呈圆形或类圆形14例,略呈浅分叶状4例。CT平扫密度均匀15例,2例可见数量不等的沙粒状钙化,1例病灶边缘可见空气新月征;增强后各病灶均有轻中度不均匀强化。结论:PSH的CT表现有一定的特异性,CT增强检查能够为其诊断提供较多有价值的信息。
英文摘要:Objective: To investigate the value of CT in the diagnosis of pulmonary sclerosing hemangioma (PSH). Methods: The clinical data of 18 cases of PSH diagnosed by surgery and pathology were analyzed retrospectively.All patients underwent multislice computed tomography (MSCT) enhanced examination, 8 cases of them underwent CT scan first. Results: CT revealed a single lesion in all of the 18 PSH cases. The diameter of the lesions ranged from 1.4 cm to 7.6 cm, with an average of 3.5 cm. PSH lesions were round or oval in 14 cases, slightly lobulated in 4 cases. Unenhanced CT scan showed that masses were homogeneous in 15 cases, 2 cases were with flecks of granular calcification, 1 case had air trapping zone in the margin. All lesions showedheterogeneous enhancement. Conclusion: The CT findings of PSH has some specificity, and enhanced CT was valuable for the diagnosis of PSH.
