摘要:
目的：分析多层螺旋CT（MSCT）平扫及增强扫描在诊断肺硬化性血管瘤（PSH）中的应用价值。方法：对14例确诊为PSH患者的MSCT平扫及增强扫描图像进行分析，观察病灶位置、大小、形态、边缘、密度、强化特征、病灶周边情况、是否合并肺门及纵膈淋巴结肿大等影像表现。结果：14例均为单发孤立病灶，病灶大小1.1 cm×1.2 cm~4.0 cm×5.6 cm。11例形态规则，未见分叶及毛刺征象，3例为类圆形伴浅分叶，未见毛刺征象；11例病灶密度均匀，表现为软组织密度影，3例病灶密度欠均匀，表现为小斑片状略低密度区；增强扫描11例平扫密度均匀，增强扫描均匀强化，3例不均匀明显强化；14例患者病灶增强后动脉期均为中等强化，且随时间延迟强化幅度增加；薄层重建及多平面重建12例病灶边缘清晰，周围肺野未见卫星灶及“胸膜凹陷征”，2例病灶前缘可见“尾征”，3例病灶边缘可见“晕征”，10例可见“贴边血管征”，4例可见“空气新月征”；仅1例患者首诊肺门及纵膈淋巴结肿大；7例诊断为PSH，3例诊断为炎性假瘤，1例诊断为结核瘤，1例诊断为错构瘤，2例诊断为周围型肺癌。结论：MSCT平扫及增强扫描可进一步显示PSH病变细节的特征表现，可提高术前诊断准确率。
Abstract:
Abstract: Objective To analyze application value of multi-slice spiral CT (MSCT) plain scan and enhanced scan in diagnosis of pulmonary sclerosing hemangioma (PSH). Methods MSCT plain scan and enhanced scan images from 14 patients who were confirmed with PSH were analyzed. The imaging findings such as location, size, shape, margin, density of lesions, enhancement features, conditions around lesions, and the presence or absence of hilus pulmonis and mediastinal lymphadenectasis were observed. Results All the 14 cases were single isolated lesions with lesions size of 1.1 cm×1.2 cm-4.0 cm×5.6 cm. There were 11 cases with uniform lesion density, showing soft tissue density shadow and 3 cases with uneven lesion density, showing small patchy slightly low-density area. The enhanced scan showed that there were 11 cases with uniform density and uniform enhancement, and 3 cases with uneven enhancement. After lesions enhancing, all 14 cases have moderate enhancement in arterial phase. With time delay, enhancement amplitude was increased. After the thin-layer reconstruction and multi-plane reconstruction, there were 12 cases with clear lesion margin and no satellite lesions or pleural indentation sign in surrounding lung fields. There were 2 cases with tail sign in leading edge, 3 cases with halo sign in border, 10 cases with welt vascular sign, and 4 cases with air crescent sign. There was only 1 case with hilus pulmonis and mediastinal lymphadenectasis in the first diagnosis. There were 7 cases diagnosed with PSH, 3 cases diagnosed with inflammatory pseudotumor, 1 case diagnosed with tuberculoma, 1 case diagnosed with hamartoma, and 2 cases diagnosed with peripheral lung carcinoma. Conclusion MSCT plain scan and enhanced scan can further show characteristic features of PSH lesions and improve accuracy of preoperative diagnosis.
