本研究旨在确定乳腺磁共振（MR）成像的乳房外发现的患病率，我们回顾性分析了828例连续患者（女性/男性; 821/7;平均年龄50 ± 11岁）接受乳腺MR成像的数据集。最常见的临床指征是评估已知乳腺肿瘤患者的病变程度（n=380，46%），常规成像中表现为可疑结果（n=331，40%），评估乳腺癌高危女性43例（5%）隆乳后（74例（9%）），282/828例（34%）患者出现了侧支病变。在这282例患者中，检测到480个偶发病变。最常见的部位是肝脏（231/480; 48%）。在480例附带结果中，66例（38例患者中的14%）被归类为重要的，值得进一步研究。这些包括26个转移性骨病变，15个纵隔/腋窝淋巴结，6个转移性肺病变，5个转移性肝病变，4个肺炎，2个升主动脉瘤，2个肾上腺腺瘤，1个背部神经纤维瘤，1个多发性骨髓瘤，1个纵隔淋巴瘤，1个胸骨淀粉样变性，1例左心室扩张和1例左心室脂肪瘤。乳房MR成像上乳房外表现的患病率很高。检查的评估不仅应关注乳腺野，还应考虑乳房外的发现，以避免不当的管理和可能的法律的问题。
This study sought to determine the prevalence of extramammary findings on magnetic resonance (MR) imaging of the breast.We retrospectively reviewed the data sets of 828 consecutive patients (F/M; 821/7; mean age, 50 +/- 11 years) who underwent breast MR imaging. The most common clinical indication was assessment of lesion extent in patients with known breast tumour (n=380, 46%), characterisation of equivocal findings at conventional imaging (n=331, 40%), evaluation of women at high risk for breast cancer (n=43, 5%) and following breast augmentation therapy (n=74, 9%).Collateral findings were found in 282/828 (34%) patients. In those 282 patients, 480 incidental lesions were detected. The most common localisation was the liver (231/480; 48%). Of the 480 collateral findings, 66 (14% in 38 patients) were classified as significant and deserving further investigation. These comprised 26 metastatic bony lesions, 15 mediastinal/axillary lymph nodes, six metastatic lung lesions, five metastatic liver lesions, four pneumonitis, two aneurysms of the ascending aorta, two adrenal adenomas, one neurofibroma of the back, one multiple myeloma, one mediastinal lymphoma, one sternal amyloidosis, one left ventricular dilatation and one trapezium lipoma.There is a high prevalence of extramammary findings on breast MR imaging. Evaluation of the examination should focus not only on the breast fields but also consider extramammary findings to avoid inappropriate management and possible legal issues.
