目的探讨肺硬化性血管瘤的CT诊断及鉴别诊断,以提高对本病的认识。方法搜集本院经手术病理证实的15例肺硬化性血管瘤病例,分析其CT表现。结果 PSH好发于中年女性,CT表现为肺周围型孤立性圆形、类圆形结节或肿块影,密度欠均匀,边缘光滑,无深分叶征象,CT增强扫描病灶明显均匀强化,灌注曲线为平台型。结论 PSH在CT平扫时具有一般良性肿瘤的特征,动态增强扫描对其诊断有较高价值,病灶周围出现“贴边血管征”及“空气新月征”更有助于肺硬化性血管瘤的诊断。
Objective To investigate the CT diagnosis and differential diagnosis of pulmonary sclerosing hemangioma in order to improve the understanding of this disease. Methods We collected 15 cases of pulmonary sclerosing hemangiomas confirmed by surgery and pathology in our hospital and analyzed their CT findings. Results The onset of PSH occurred in middle-aged women. CT showed a solitary circular or round nodule or mass with a uniform density, smooth edges and no deep lobe sign. The lesions of CT enhancement scan were significantly and uniformly enhanced, Pouring curve for the platform type. Conclusions PSH has the characteristics of benign tumors in CT scan. Dynamic contrast-enhanced scan is of great value in the diagnosis of PSL. The appearance of PSL and Sclerosing hemangioma diagnosis.
