摘　　要：目的观察乳腺假血管瘤样间质增生(PASH)超声和乳房X线片表现。方法纳入51例经病理证实PASH患者,共54个结节,观察其超声及X线表现。采用Newcombe法评价超声及X线结节检出率的差异。结果54个乳腺PASH结节中,26个(26/54,48.15%)经超声评价为乳腺影像报告和数据系统(BI-RADS)3类、28个51.85%(28/54)为BI-RADS 4类;其中41个(41/54,75.93%)表现为低回声;31个为椭圆形(31/54,57.41%);29个(29/54,53.70%)边缘不光整;52个(52/54,96.30%)结节内未见钙化;44个(44/54,81.48%)未见血流信号。30例接受X线检查,15例未见占位,其中3例仅显示腺体密度不对称;12例(12个结节)可见无钙化的高密度影;7个(7/12,58.33%)边缘清晰。超声及X线对乳腺PASH结节的检出率分别为100.00%(54/54)和40.00%(12/30),95%CI为(26.69%,63.86%)(P<0.05)。结论乳腺PASH超声及X线表现均缺乏特异性,但超声检出率显著高于X线。Objective To observe the ultrasonic and mammographic features of pseudoangiomatous stromal hyperplasia(PASH)of the breast.Methods A total of 51 patients with pathologically diagnosed PASH(54 nodules)were enrolled,and the ultrasonic and mammographic features were observed.The proportion difference of the detection rate of PASH of ultrasound and mammography was compared with Newcombe method.Results Among 54 PASH nodules of the breast,26(26/54,48.15%)were classified with ultrasound as breast image reporting and data system(BI-RADS)3,28(28/54,51.85%)were classified as BI-RADS 4.Hypoechoic were detected in 41(41/54,75.93%)nodules,while 31(31/54,57.41%)nodules were oval-shaped,the edges of 29(29/54,53.70%)were not circumscribed.No calcification was observed in 52(52/54,96.30%),nor blood supply in 44(44/54,81.48%)nodules.Among 30 cases underwent mammograms,12(12/30,40.00%)nodules showed high density without calcification,58.33%(7/12)were fine circumscribed,3 cases showed only asymmetric gland density,while no obvious abnormalities were found in 15 cases.The detection rate of ultrasonography and mammography for breast PASH was 100.00%(54/54)and 40.00%(12/30),with 95%CI(26.69%,63.86%)(P<0.05).Conclusion Both ultrasonic and mammographic features of breast PASH lacked specificity,but the detection rate of breast PASH of ultrasound was significantly higher than that of mammography.
