Figure 3. The initial surgery was breast-conserving surgery (BCS) plus sentinel node biopsy (SNB) 14.5 years ago without radiotherapy (Patient 4). Lymphoscintigraphy and single-photon emission computed tomography (SPECT/CT) showed radioisotope accumulation only in the ipsilateral axilla at 3 h after 99mTc-phytate injection. An oblique planar image in early (A) and delayed phases (B). The red arrow indicates an accumulation in the axillary lymph node. SPECT/CT image at 15 min showing only injection site (C) and the late phase in SPECT/CT (D), and isotope was accumulated in the axilla (red arrow).
