目的：探讨 MSCT 扫描并双期增强扫描在诊断肺硬化性血管瘤(PSH)中的价值。方法回顾性分析2012年3月—2014年6月9例经病理证实 PSH 的 MSCT 平扫及双期增强扫描资料,观察病灶的形态学、密度(CT值)、与周围组织结构的关系及双期增强特点。结果本组9例 PSH 病灶均为随机分布、单发、边界清楚、圆形或卵圆形灶,7例边缘光滑,2例可见浅分叶,均未见毛刺,6例密度均匀,9例均未见钙化或囊变,7例见支气管血管束挤压征象(贴边血管征),3例见空气新月征,2例可见周围肺野磨玻璃影；双期增强扫描示中度强化并显示随着时间延长而增强的特点。结论 MSCT 扫描并双期增强扫描有利于进一步显示病变细节的 CT 表现,可提高影像诊断与病理诊断符合率,降低误诊率。

Objective To assess the value of plain and biphasic contrast enhancement MSCT scanning in diagnosis of pulmonary sclerosing hemangioma (PSH). Methods The data of plain and biphasic contrast enhancement MSCT scanning from 9 PSH patients confirmed by pathology admitted during March 2012 and June 2014 was retrospectively analyzed. The focal morphology, density (CT value), the relationship with the surrounding tissue structures and characteristics of biphasic contrast enhancement were observed. Results The PSH lesions of the 9 cases were randomly distributed, single, clear boundary, round or ovoid, in which 7 cases showed smooth edge and 2 cases showed visible light points, but no sentus was found in any case. Uniform density was found in 6 cases; calcification or cystic change was not found in any case; bronchus signs of vascu-lar bundle extrusion (welt blood vessels) were found in 7 cases; air crescent signs were found in 3 cases; ground glass shadow of peripheral lung field was found in 2 cases. Biphasic contrast enhancement scanning showed that it was moderate enhance-ment and the enhancement was strengthened with time. Conclusion The plain and biphasic contrast enhancement MSCT scanning can help to find further lesion changes in details, improve the coincidence rates of medical imaging and pathological diagnosis and reduce the misdiagnosis rate.
