(A) Computed tomography on the 12th day post-admission shows a tumoral lesion suspicious of infiltration into the right first rib and intercostal muscles, with changes in the density of the lung parenchyma around the tumor. These findings are suggestive of extension of the lesion along the lymphatic vessels and stroma. (B) 8 F-Fluorodeoxyglucose positron emission tomography-computed tomography on the 17th day post-admission shows a tumoral lesion with a high degree of accumulation with a maximum standardized uptake value = 16.73
