目的 提高CT诊断肺硬化性血管瘤的认识。方法 手术和病理证实的肺硬化性血管瘤9例,男性1例,女性8例。年龄从25到56岁,平均年龄为41.1岁。全部病例均作CT平扫和增强扫描,并分析其CT表现。结果 肺硬化性血管瘤的CT表现为孤主性肿块。边界清晰,边缘光整,增强扫描时肿块密度均匀或不均匀强化,少数病例可见空气新月征。肿块周围肺组织、肺门及纵隔未见异常。结论 CT薄层增强扫描,有助于肺硬化性血管瘤的诊断。
Objective To improve the diagnosis of pulmonary sclerosing hemangiomas by CT. Methods 9 cases of pulmonary sclerosing hemangiomas were confirmed by surgery and pathology. There were 1 male and 8 female. Ages range from 25 to 56 years, with an average age of 41.1 years. CT scans and enhanced scans were performed in all cases and their CT findings were analyzed. Results CT of pulmonary sclerosing hemangiomas showed a lone mass. The borders are clear, the edges are smooth, and the density of the mass increases evenly or unevenly during the scan. In a few cases, the signs of the air are visible. No abnormalities were found in the lung tissue, hilar and mediastinum around the mass. Conclusion CT thin-layer enhanced scan is helpful for the diagnosis of pulmonary sclerosing hemangiomas.
