肺硬化性血管瘤CT诊断及鉴别诊断

目的探讨肺硬化性血管瘤（PSH）的CT诊断及鉴别诊断,以提高对本病的认识和诊断率。方法回顾性分析我院经手术病理证实的7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表现为肺内孤立圆形、类圆形结节或肿块,密度尚均匀,边界光整。CT增强扫描病灶呈明显均匀强化,且持续强化。结论 PSH具有一般良性肿瘤的CT表现,动态增强扫描对其诊断有较高价值;病灶周围出现＂空气新月征＂及＂贴边血管征＂更有助于对肺硬化性血管瘤的诊断。

CT diagnosis and differential diagnosis of the pulmonary sclerosing hemangioma

Objective To investigate the pulmonary sclerosing hemangioma （PSH） of the CT performance features, designed to increase awareness of PSH imaging to improve preoperative diagnosis. Methods The clinical data of 7patients with PSH in our hospital,including symptoms,radiologieal examinations. The diagnosis of PSH was confirmed by histological examination. Results PSH should be considered in young and middle-aged female patients. On CT, the lesion presented as well-defined, round and oval shaped mass or nodule, a homogeneous soft tissue mass on unenhanced CT. Homogeneous enhancement after contrast administration; on delayed phase scans, some of them demonstrated late enhancement. Conclusion PSH in the CT scan is generally benign characteristics. The disease can be preoperatively diagnosed combined with air-trapping zone, vessels at its periphery within images （especially on CT）.
