A 52-year-old male patient, presented with history of right lung neoplastic mass (poorly differentiated adenocarcinoma) under treatment and referred for follow-up after 4 months, showing metabolic and morphological regression of the right upper lung lobe hypermetabolic neoplastic mass (arrow) currently achieving 6.4 SUVmax and measuring 7.5 × 8.5 cm (compared to 14.5 SUVmax and 10 × 8 cm previously). It is seen merging with the adjacent hypermetabolic mediastinal lymph nodes, currently developing large central photopenic area of necrosis (arrow head).
