A 58-year-old woman was diagnosed with infiltrating ductal carcinoma in 2012. It was
operatively removed by means of lumpectomy with selective sentinel node biopsy and
was free of metastases. Subsequently, the patient received chemotherapy and adjuvant
radiotherapy. In 2015 a new periareolar mass in the left breast was found and diagnosed
by core needle biopsy as invasive duct carcinoma. After receiving chemotherapy treatment
and verifying neither regional nor distant disease were discovered, lymphoscintigraphy
was performed with periareolar injections of 74 MBq 99mTc-nanocolloid in the left
breast. Planar lymphoscintigraphy imaging, and single photon emission computed tomography/computed
tomography (Figure, A and B) performed 2 hours after injection (arrow head) revealed 3 sentinel lymph nodes (arrows)
in the contralateral axilla.
