A 58-year-old woman with previous right breast carcinoma treated with lumpectomy, right axillary clearance, chemo-radiotherapy, and adjuvant hormonal therapy underwent a lymphoscintigraphy for a new right breast lesion. On planar images, an alternate route of lymphatic drainage was observed to the right internal mammary chain and the left axilla. A chest SPECT/CT was performed to confirm the location of the sentinel nodes. The patient underwent a right mastectomy and left axillary sentinel lymph node biopsy, which showed no evidence of lymphovascular invasion. Combining planar imaging and SPECT/CT techniques can accurately identify sentinel lymph nodes at their new unpredicted location.
一位 58 岁的女性，曾患有右侧乳腺癌，接受了保乳手术、右侧腋窝清扫术、化疗-放疗和辅助激素治疗，因新的右侧乳腺病变进行了淋巴闪烁显像。在平面图像上，观察到另一条淋巴引流途径到右侧内乳链和左侧腋窝。进行胸部 SPECT/CT 以确认前哨淋巴结的位置。患者接受了右侧乳房切除术和左侧腋窝前哨淋巴结活检，未见淋巴管侵犯的证据。结合平面成像和 SPECT/CT 技术可以准确识别新的、未预测到的前哨淋巴结位置。
