肺硬化性血管瘤的CT表现

CT MANIFESTATIONS OF PULMONARY SCLEROSING HEMANGIOMA

目的分析肺硬化性血管瘤的CT影像学表现,提高对其认识及影像征象正确性。方法回顾性分析经手术病理证实的8例肺硬化性血管瘤的CT影像学表现及其临床表现。结果 8例患者均为单发病灶,病灶的直径7～36mm(平均26mm),均为圆形(6例)和椭圆形(2例),密度均匀,未见明显坏死区及钙化影,所有病灶均未见毛刺。增强后1例病灶为不均匀强化,其余7例病灶为均匀强化。2例病灶合并有贴边血管征,1例病灶周缘伴有晕征。结论肺硬化性血管瘤常见于中年女性,常表现为密度均匀、单发,边界清楚的富血供肺部肿块或结节,具有一定相对特异性的CT表现。

Objective To analyze the CT image of pulmonary sclerosing hemangioma, to increase the correctness of its imaging diagnosis. Methods The CT image of 8 cases confirmed by pathological diagnosis as pulmonary sclerosing hemangioma, combined with their chnical symptoms and signs were retrospectively reviewed. Results All the cases were single, round or oval lesions, sizes ranging from 7mm to 36mm （average 26mm）, no calcification and burr. One case showed inhomogenous enhancement, 7 cases showed homogenous enhancement in enhanced scans. 2 cases had vascular syndrome, and 1 case had Halo sign. Conclusion Pulmonary sclerosing hemangioma is a common disease of middle-aged women, often manifests as a uniform density, single nidus, sharply defined, rich blood supply lung tumor or nodule, and can be specific displayed by CT image.
