  • Objective:To describe and comparatively assess multi-sliced computed tomography(MSCT) imaging findings and pathological features of pulmonary sclerosing pneumocytoma(PSP). Method:MSCT findings and pathological data from 15 patients(2 male and 13 female, aged 17-73 years) pathologically confirmed PSP were retrospective reviewed. Result:All of those PSPs were juxta-pleural, solitary masses demonstrated on MSCT. Lesion appeared as were well-defined, rounds or ovoid masses in 8 cases(53%), as lobular masses in 6 cases(40%), as ill-defined, irregular mass in 1 case(7%). The air crescent sign(20%), halo sign(25%), overlying vessel(20%), and tail sign(7%) in the tumors were also demonstrated in the cohort. 10 tumors(67%) enhanced homogeneously compared with four tumors(33%) which enhanced heterogeneously in the artery phase and delayed enhancement in venous phase. Conclusion:PSP is an uncommon benign tumor, occurring predominantly in middle-aged females, the relatively characteristic MSCT findings can improve the accuracy of preoperative diagnosis.
