| 目的 分析乳腺单纯型黏液癌(PMBC)的MRI影像学表现。方法 回顾性分析经手术病理证实的23例PMBC患者的MRI特点。结果 PMBC的MR多表现为卵圆形肿块(18/23,78.26%),多数病灶边缘光整(15/23,65.22%);T1WI呈等低信号(22/23,95.65%)或均匀低信号(1/23,4.35%)。肿瘤的强化方式为环形强化(15/23,65.22%)、不均匀强化(7/23,30.43%)及无强化(1/23,4.35%)。早期增强率为(103.90±50.50)%。时间-信号强度曲线以流入型为主(17/22,77.27%);T2WI呈明显高信号(23/23,100%),多伴内部低信号分隔(21/23,91.30%)。DWI均呈明显高信号,ADC值为(2.05±0.38)×10-3 mm2/s。结论 PMBC的MR表现具有一定特征性。 |

| Objective To analyze MRI features of pure mucinous breast carcinoma (PMBC). Methods MR characteristics of 23 PMBC patients confirmed by postoperative pathology were analyzed retrospectively. Results MRI showed oval shape in 18 patients (18/23, 78.26%) and circumscribed margin in 15 patients (15/23, 65.22%). On T1WI, 22 cases (22/23, 95.65%) had hypo-and iso-intensity, and only 1 (1/23, 4.35%) with homogeneously low signal intensity. Enhancement patterns of PMBC were rim enhancement (15/23, 65.22%), heterogeneous enhancement (7/23, 30.43%) and no appreciable enhancement (1/23, 4.35%). Early enhancement rate was (103.90±50.50)%. Seventeen cases (17/22, 77.27%) showed persistent enhancing pattern on time-signal intensity curve. On T2WI, most of them presented strongly high signal intensity (23/23, 100%), which accompanied with dark internal septation (21/23, 91.30%). All tumors showed high signal intensity on DWI. The mean ADC value was (2.05±0.38)×10-3 mm2/s. Conclusion The MR characteristics of PMBC are helpful for diagnosis and differential diagnosis. |
