摘　　要：目的分析乳腺炎的影像特征。方法回顾性分析58例病理证实为乳腺炎的乳腺x线、超声及MRI表现特点，并根据影像特征判定乳腺影像报告和数据系统（BI-RADS）分级。30例行乳腺x线检查，49例行超声检查，58例均行MRI检查。结果6例乳腺X线和2例超声检查无明确阳性发现，MR图像上可以显示所有病灶。乳腺炎在乳腺x线像上多表现为非对称性致密（16／30，53．3％），超声声像图上多呈单发或多发相互连通或不连通的低回声肿块样病灶（34／69，69．4％）；增强MR图像上，48例（48／58，82．8％）患者表现为非肿块样强化，且多表现为多发区域样分布（66．7％，32／48）及内部呈相互连通或不连通的集丛环状强化（63．1％，31／48）。在58例患者中，时间．信号强度曲线呈I型及Ⅱ型者分别为28（48．3％）和29例（50．O％）。BI-RADS分类为0级（33．3％，10／30）在乳腺X线摄影、4a类在超声成像（36．7％，18／49）及MRI检查（56．9％，33／58）中所占的比例最大。结论乳腺炎的x线摄影及超声表现无特异；在增强MR图像上呈多发的区域样分布，及相互连通或不连通的集丛环状强化的非肿块样强化。Objective To describe the radiological features of mastitis. Methods Imaging findings were retrospectively reviewed in 58 women with mastitis, which was confirmed by pathological results. The imaging features were described according to the BI-RADS （ breast imaging reporting and data system）. All 58 patients had preoperative MRI,while 49 of them were examined with sonograms and 30 with mammograms preoperatively. Results Overall, no remarkable findings were reported on 6 mammography and 2 sonography examinations, but all 58 lesions were identified on MRI in our study. Asymmetrical density （n = 16,53.3% ） on mammograms and solitary or multiple separated/contiguous hypoechoic mass-like lesions （n =34,69.4% ） on ultrasound were the most common signs of mastitis. On enhanced MR images, 82. 8 % （48/58） patients showed non-mass-like enhanced lesions. Multiple, regional enhancement （ 66. 7 % , 32/48 ） and separated or contiguous, clumped, rim-like enhancement （ 63.1% , 31/48 ） were the most common manifestations in non-mass-like enhanced lesions. Of the 58 patients,type I and type 11 time- signal intensity curve were detected in 48. 3% and 50.0% of the patients, respectively. BI-RADS 0 had the highest frequency in reports on mammography （33.3%, 10/30）, while category 4a was most frequent on sonography （36. 7% ,18/49） and also on MRI （56. 9% ,33/58）. Conclusion The imaging findings from mammography and US are non-specific for mastitis, therefore, MR can be helpful in the diagnosis, especially in the presence of non-mass-like enhancement that are multiple, regional, separated, or contiguous, clumped, and tim-like.
