Nodule in the right lung apex and percutaneous biopsy of the same: in A, positron emission tomography-CT (PET-CT) scan showing the nodule (arrow); in B, CT scan showing the point of insertion of the coaxial needle (arrow); in C, PET-CT scan after 6 months of follow-up, showing an 18F-fluorodeoxyglucose-avid soft tissue mass; and in D, CT scan after 6 months of follow-up, showing bone erosion of the right third rib posteriorly (arrow).

A 56-year-old male patient underwent percutaneous biopsy of a nodule in the right lung apex (Figure 1A). The tip of a 19-gauge coaxial needle was positioned in the posterior chest wall (Figure 1B), and six samples of the lesion were obtained with a 20-gauge core needle. At 6 months of follow-up, a positron emission tomography-CT scan of the chest showed an 18F- fluorodeoxyglucose-avid soft tissue mass (Figure 1C) in the T3-4 interspace, along the biopsy tract, as well as bone erosion of the right third rib posteriorly (Figure 1D), suggesting tumor seeding.
