To demonstrate the computed tomography (CT) features of pulmonary sclerosing haemangiomas.
Six pathologically proven sclerosing haemangiomas were included in this retrospective review. Patients consisted of five women and one man aged 20-54 years (mean, 34.5 years). Their CT features were recorded according to enhancement patterns and the presence of a tail sign, prominent pulmonary artery sign, air-trapping sign, presence of calcification or cystic spaces, consolidation, and interstitial infiltration. The predominant composition of an individual sclerosing haemangioma was documented by means of microscopy.
Inhomogeneous enhancement was frequently present and depended on the various compositions of the tumours, especially those in sclerotic and predominantly papillary predominant types. The presence of a tail sign, intra-tumoural cystic areas, and a prominent artery sign were the frequent features in our cases.
Sclerosing haemangioma should be considered in young or middle-aged female patients whose CT images show them having an inhomogeneous enhancing soft tissue mass with a smooth outline and with above the aforementioned features.
探讨肺硬化性血管瘤的计算机断层扫描（CT）特征。
本回顾性研究纳入6例经病理证实的硬化性血管瘤患者。患者包括5名女性和1名男性，年龄20 - 54岁（平均34.5岁）。根据增强模式以及是否存在尾征、肺动脉突出征、空气潴留征、钙化或囊腔、实变和间质浸润等记录其CT特征。通过显微镜记录单个硬化性血管瘤的主要成分。
不均匀强化较为常见，这取决于肿瘤的不同组成部分，尤其是硬化型和以乳头为主型。尾征、瘤内囊变区和肺动脉突出征是我们病例中的常见特征。
对于CT图像显示为轮廓光滑的不均匀强化软组织肿块且具有上述特征的中青年女性患者，应考虑硬化性血管瘤的可能。
