| 目的 分析原发性乳腺淋巴瘤的影像学表现。方法 收集经病理证实并具有完整临床资料的乳腺淋巴瘤患者15例,年龄28~77岁,平均(49.5±3.9)岁。由2名影像科医师共同阅片,评价乳腺X线、超声、CT及MR特征。结果 15例患者共17个病灶,病灶大小1.3~12.0 cm。X线检查的10例患者中,1例未见异常,1例因病变位置特殊显示不佳而无法评价,余8例共发现10个病灶,均表现为非毛刺性肿块,其中1个伴点状钙化,3个伴乳晕区皮肤增厚。接受超声检查的9例患者中,共发现11个病变,6个表现为高低混杂回声;7个可探及丰富血流信号;2个边缘可见高回声晕;4个伴后方回声增强。接受CT检查的8例患者中,2例平扫表现为弥漫性乳腺体积增大,6例接受增强扫描者,4例表现为均匀轻中度强化,2例表现为不均匀环形强化。接受MR检查的4例患者中,T2W脂肪抑制表现为稍高信号3例,高信号1例。DWI均显示扩散受限明显。1例均匀强化,3例不均匀强化。时间-信号曲线示3例为流出型,1例为缓升型。结论 原发性乳腺淋巴瘤的影像学表现具有一定特征性。DWI可能有助于诊断乳腺淋巴瘤。 |

| Objective To analyze the imaging features of primary breast lymphoma. Methods Totally 15 patients (age 28—77, the mean age years old) with primary breast lymphoma confirmed histopathologically were retrospectively reviewed. Imaging features of mammography, ultrasonogrphy, CT and MR were evaluated by two radiologists. Results Seventeen lesions sized 1.3—12.0 cm were found in 15 patients. Mammograms of 10 patients showed 10 nonspiculated masses in 8 patients, 1 punctate calcification lesion, and aorealar skin thickness in 3 lesions. No abnormality was found in 1 patient, while poor lesion demonstration because of special location was found in the other patient. Nine patients underwent ultrasonography, which found 11 lesions. The typical masses were mixed hyper- and hypoechoic in 6 lesions, and hypervascular in 7 lesions; two lesions demonstrated echogenic boundary, and 4 had posterior enhancement. Eight patients underwent CT. Plain CT of 2 patients showed diffuse enlargement of the breast; enhanced CT of 6 patients showed mildly to moderately homogenous enhancement (n=4) or heterogeneous enhancement (n=2) of the lesions. Four patients underwent MR. T2WI demonstrated high signal lesion in 1 patient, while moderate signal lesions in the other 3 patients; dynamic enhanced MR imaging of 4 patients showed intensely and heterogeneously enhancing masses in 3 patients, and homogeneously enhancing mass in the other one, while rapid enhancement and washout were observed in 3 patients, and persistent enhancement of the lesion was observed in 1 patient. Conclusion Primary breast lymphoma has some imaging characteristics. DWI may be helpful to the diagnosis of breast lymphoma. |
