肺硬化性血管瘤的CT诊断与鉴别

CT diagnosis and differental diagnosis of sclerosing hemangioma of the lung

目的 :提高肺硬化性血管瘤 (SHL)的CT诊断及鉴别诊断水平。方法 :搜集经手术病理证实的SHL 4例 ,均为女性 ,年龄 42～ 5 7岁 ,平均 5 0 .75岁。全部病例均作CT平扫及增强扫描 ,并行靶病灶的薄层扫描 ,对其表现进行分析。结果 :SHL好发于中年女性 ,典型CT表现为肺内周围型孤立结节 ,边界清晰 ,边缘光整 ,周围肺野清晰 ,肺门及纵隔无异常改变 ;增强扫描呈明显均匀强化。病理上分为乳头区、实变区、血管瘤区及硬化区。结论

Objective:To study the CT diagnosis and differential diagnosis of sclerosing hemangioma of the lung(SHL). Mathods:Four cases of sclerosing hemangioma of the lung confirmed by surgery and pathology were retrospectively studied. All cases were female in the group(age range 42～57 years,mean 50.85 ).The plain CT and contrast enhanced CT were performed in all cases,and thin section CT was used for all lesions.The CT findings of all cases with SHL were analyzed.Results:SHL usually occured in female patients of middle ages;the typical CT findings of SHL were solitary nodule located in peripheral lung with clear and smooth margin.The pulmonary parenchyma outside the lesions was clear,hilum and mediastinum were normal.CT demonstrated homogeneous enhancement. The tumors showed a mixture of the following four histological patterns:papillary,solid,hemangioma like and sclerotic regions.Conclusion:CT especially thin section CT with contrast media is of benefit in diagnosis and differential diagnosis of SHL.
