(a and b) Computed tomography of the thorax demonstrated a 1.5 cm spiculated left upper lobe mass and a 1.2 cm right upper lobe nodule. Positron-emitted tomography-computed tomography confirmed a 1.3 cm left upper lobe mass with a standardized uptake value of 4.2 and a mildly avid right upper lobe nodule

Positron-emitted tomography (PET)-CT demonstrated no evidence of mediastinal or hilar lymphadenopathy [Figure 1a and b].
(a and b) Follow-up computed tomography of the thorax and positron emitted tomography-computed tomography post-left upper lobectomy demonstrated only a 12 mm focus of residual linear scarring and faint fluorodeoxyglucose avidity at the site of the previous right upper lobe nodule

These findings were confirmed on PET imaging which demonstrated only faint FDG-avidity and residual linear scarring at the site of the previous right upper lobe nodule [Figure 2a and b].
