SPECT/CT reinforces the role of lymphoscintigraphy in breast cancer by solving some cases with difficult reading on planar scintigraphy. An 80-year-old woman was referred to our institution for management of a screen-detected, nonpalpable, invasive lobular carcinoma of lower inner quadrant of the left breast. Lymphoscintigraphy was performed before surgery. Planar images showed an axillary sentinel node and 2 medially located hot spots. SPECT/CT allowed determining that one of the extra-axillary drainage sites was to the internal mammary basin, while the second corresponded to a mediastinal lymph node. Although this drainage was unexpected, mediastinum is a common site of breast cancer recurrence.
SPECT/CT 通过解决某些平面闪烁显像难以阅读的病例，增强了淋巴闪烁显像在乳腺癌中的作用。一位 80 岁女性因左乳下内象限可触及的浸润性小叶癌被转诊至我院治疗。在手术前进行了淋巴闪烁显像。平面图像显示腋窝前哨淋巴结和 2 个位于内侧的热点。SPECT/CT 确定其中一个额外的腋窝引流部位到内乳盆，而第二个则对应纵隔淋巴结。尽管这种引流是出乎意料的，但纵隔是乳腺癌复发的常见部位。
