摘　　要：目的探讨肺硬化性血管瘤(pulmonary sclerosing hemangioma,PSH)的MSCT表现特征和病理基础,以提高对该病的进一步认识。方法回顾性分析13例经穿刺或手术病理证实为肺硬化性血管瘤患者的MSCT表现及相关病理。结果10例为单发实性边界清晰类圆形结节或肿块,仅1例多发,2例病灶周围可见"晕征"。11例直径小于3cm,最大病灶直径约10cm,最小者直径约0.8cm。强化情况,明显强化6例,其中3例不均匀强化,另4例为渐进性强化,1例未见明显强化。结论肺硬化性血管瘤MSCT表现具有很多种特征性,再加上MSCT的MPR技术的运用,不仅能更好地显示病灶的形态学特征及其与邻近血管、支气管的关系,而且病灶动脉期的高度强化可以反映PSH的特征性病理学特点,有利于该病变的诊断。Objective To investigate the Multisliecs Helieal CT imaging characteristics of pulmonary sclerosing hemangioma （PSH） and its pathological basis, so as to improve the further understanding of the disease. Methods MSCT features and preoperative diagnostic accuracy were retrospectively analyzed of 13 patients with pathologically proven PSHs after surgery.Results 10 images in our study presented solitary pulmonary nodules or masses, only l case had two nodes, 2 cases of lesions had Halo sign. 11 cases less than 3 cm diameter, Maximum lesions diameter about 10 cm, minimum 0.8 cm. After contrast agent administraction, 6 cases showed prominent enhancement, 3 case with imhomogeneous enchancement, and another 4 case with progressive enancentent, 1 case with unconspicuous enchancement. Conclusion The MSCT image features of PSH have mutiple characteristics and combined with MPR technique of MSCT, not only display morphology and relations with nearby blood vessels and bronchi of PSH, but also reflect net enhancement on vascular phase which indicate distinctive pathology of PSH, which is helpful in diagnosis of PSH.
