Abstract
We present MDP bone scan findings of radiation pneumonitis in a 45-year-old woman with invasive ductal carcinoma of the right breast, classified as stage IIIa, T3N2M0. The patient underwent a modified radical mastectomy, neoadjuvant chemotherapy, and subsequent radiotherapy, receiving the last session 7 months before the bone scan. Whole-body images acquired 3 hours postinjection of 20 mCi (730 MBq) 99m Tc-MDP showed incidentally increased uptake in the right hemithorax, confined to the lung parenchyma of the right lung on SPECT/CT images.
