摘　　要：目的分析硬化性肺泡细胞瘤(PSP)CT表现并与病理进行对照,提高对该病的术前诊断水平。方法收集经手术病理证实的11例PSP患者资料,回顾分析了PSP的CT表现和临床病理特点,术前均经常规CT平扫及增强扫描。结果 11例患者术后病理诊断为肺硬化性血管瘤,均为单侧、单发。CT表现为:7例血管贴边征、3例空气新月征、3例晕征、2例尾征、1例显著肺动脉征。5例PSP延迟强化。结论 PSP好发于女性,影像表现有一定的特征,但缺乏特异性征象,常为孤立性结节,边界清楚,常为类圆形,可有浅分叶状,钙化少见,强化后呈延迟强化,综合分析可提高术前诊断,确诊尚依靠病理学检查。Objective To analyze the CT findings of pulmonary sclerosing pneumocytoma （PSP） and to compare those with pathology, and to improve the diagnostic accuracy. Methods We comducted retrospective analysis of 11 cases of PSP, with both CT scan and surgical pathological confirmation. Routine CT scan and enhanced scan were performed before the operation. Results 11 cases were unilateral and solitary. There were welt vessel signs in 7 cases, air meniscus sign in 3 cases, halo sign in 3 cases, tail signs in 2 cases, and prominent pulmonary artery sign in 1 case. Delayed enhancement of PSP was found in 5 patients. Con- -lusion PSP occurs in women, imaging has certain characteristics, but is lack of specific signs, often solitary nodule, clear boundary, usually round-like, maybe having a lobulated shape. Conclusion is rare, and delayed enhancement appears after inten- sification. Comprehensive analysis can improve preoperative diagnosis, and diagnosis is still dependent on pathological examination.
