case_images: PET scan displaying metabolically active lesions with corresponding pathology. LN, lymph node; IDC, invasive ductal carcinoma; TNBC, triple-negative breast cancer; NSCLC, non-small cell lung cancer; ER, oestrogen receptor; PR, progesterone receptor; PD-L1, programmed death ligand 1; EGFR, epidermal growth factor receptor.

case_images: A PET scan was performed, revealing FDG-avid lesions in the left lower lobe of the lung (LLL), right middle lobe of the lung (RML), right paratracheal lymph node (LN), subcarinal LN, right supraclavicular LN right breast, and multiple lesions on the left breast (Fig. 1). In summary, the patient was found to have right primary TNBC, left multifocal hormone receptor-positive breast cancer, left primary EGFR-mutated lung adenocarcinoma, possible right primary lung adenocarcinoma of unspecified mutational status, and a solitary metastatic lesion in the brain from one of her primary cancers (Fig. 1).
case_images: Restaging PET scan 16 months post-diagnosis showing residual metabolic activity in the previously biopsy-proven RML NSCLC and complete metabolic response at all other sites of previous activity.

case_images: PET scan 16 months post diagnosis redemonstrated a metabolically active RML nodule, but a complete metabolic and radiographical response to all other previously noted lesions (Fig. 2).
