We wanted to investigate the ability of breast MR imaging to identify the primary malignancy in patients with axillary lymph node metastases and initially negative mammography and sonography, and we correlated those results with the conventional imaging.
From September 2001 to April 2006, 12 patients with axillary lymph node metastases and initially negative mammography and sonography underwent breast MR imaging to identify occult breast carcinoma. We analyzed the findings of the MR imaging, the MR-correlated mammography and the second-look sonography. We followed up both the MR-positive and MR-negative patients.
MR imaging detected occult breast carcinoma in 10 of 12 (83%) patients. Two MR-negative patients were free of carcinoma in the ipsilateral breast during their follow-up period (39 and 44 months, respectively). In nine out of 10 patients, the MR-correlated mammography and second-look sonography localized lesions that were not detected on the initial exam. All the non-MR-correlated sonographic abnormalities were benign.
Breast MR imaging can identify otherwise occult breast cancer in patients with metastatic axillary lymph nodes. Localization of the lesions through MR-correlated mammography and second-look sonography is practically feasible in most cases.
我们旨在研究乳腺磁共振成像（MR成像）对于腋窝淋巴结转移且乳腺X线摄影和超声检查初诊为阴性的患者中识别原发性恶性肿瘤的能力，并将这些结果与传统成像进行对比。
2001年9月至2006年4月，12例腋窝淋巴结转移且乳腺X线摄影和超声检查初诊为阴性的患者接受了乳腺MR成像以识别隐匿性乳腺癌。我们分析了MR成像、与MR相关的乳腺X线摄影及二次超声检查的结果。我们对MR成像阳性和阴性的患者均进行了随访。
MR成像在12例患者中的10例（83%）检测到隐匿性乳腺癌。2例MR成像阴性的患者在随访期间（分别为39个月和44个月）同侧乳腺未发现癌症。在10例患者中的9例中，与MR相关的乳腺X线摄影及二次超声检查定位到了初次检查未发现的病变。所有与MR不相关的超声异常均为良性。
乳腺MR成像能够识别有腋窝淋巴结转移患者中隐匿性乳腺癌。在大多数情况下，通过与MR相关的乳腺X线摄影及二次超声检查对病变进行定位在实际操作中是可行的。
