（福建医科大学附属漳州市医院影像科福建漳州 363000）【摘要】目的:探讨硬化性肺泡细胞瘤(PSP)的CT特征,提高诊断水平。
方法:回顾性分析我院2007—2017年21例经手术与病理证实的PSH 临床资料和CT表现。
其中女20例，男1例，年龄12～60岁，平均年龄44.9±11岁，均行胸部CT平扫及其中19例行增强扫描。
结果：19例表现为类圆形结节或肿块，其中17例为孤立灶，2例合并肺癌；另外2例，一例表现为不规则形软组织块影、另一例为片状实变影。
PSP 影像多以孤立病灶表现为主，边缘光滑整齐。
病变直径8～56mm，平扫CT 值(17Hu～49Hu，平均CT值约34Hu)，增强扫描呈均匀或不均匀强化，大部分动脉期明显强化，净值(40～56Hu)，个别早期轻度强化者，延迟期呈持续上升强化。
结果：中年女性，孤立的边缘光滑的类圆形或椭圆形结节或肿块，密度均匀或不均匀，增强后早期明显强化，延迟持续上升强化、强化时间长为PSP强化特征。
结论:硬化性肺泡细胞瘤的CT表现有一定性别、年龄分布特点，CT扫描形态及增强检查能为诊断提供重要依据。

Zhangzhou Municipal Hospital Affiliated to Fujian Medical University Fujian Zhangzhou 363000 ,China 【Abstract】Objective To discuss the imaging feature of pulmonary sclerosing emanagioma(PSP),so that to improve the accurate rate of its diagnosis.Methods 21cases with PSP proved by surgery and pathology were enrolled.The CT findings of 21 cases including 1 males and 20 females ,ranged in age from 12 to 60,with the averagy of 44.9±11. All the cases underwent MSCT precontrast scan and 19cases received enhanced CT scan.19 cases were nodule or lump, 17 cases were single shot,2 case with both lung cancer and PSP at the same time;1 case was irregular form, 1 was patchy consolidation; Diameters of these lesions ranged from 8 to 56 mm;The CT value of precontrast was ranged from 17Hu to 49Hu,average 34Hu,All case were homogeneous or heterogeneous enhancement after contrast ministration,Most of the case was obvious enhancement,the abosolute enhancement ranges from 40 to 56 Hu.Small part was slight enhancement in arterial phase,and continuous strengthening in lag phase.Middle aged Women,single and round nodule or lump in lungs,with homogeneous or inhomogeneous density ,obvious enhancement and lasts long, is characteristic presene of PSP. Conclusion The CT image features of PSP have some characteristic in sex,age and shape,the enhanced CT scan could be helpful in diagnosis. 【Key words】Pulmonary sclerosing emanagioma; Imaging diagnosis; Computer tomography 硬化性肺泡细胞瘤(pulmonary sclerosing pneumooytoma PSP)是一种临床少见的肺部肿瘤，过去多命名为肺硬化性血管瘤，随着认识的深入，免疫组化和超微结构表明这种肿瘤来源于Ⅱ型肺泡细胞，于是在2015年肺肿瘤组织分类学正式称为硬化性肺泡细胞瘤。
