Axial nonenhanced CT in a 73-year-old man 3 weeks after FFF reconstruction shows tram-track vascular calcification in the wall of the peroneal artery (arrows), a pattern typical of atherosclerosis. This appears distinctly different from the attenuated, linear, continuous, or multisegmented patterns that were observed in patients with periosteal ossification. Pedicle ossification is not evident on this scan, and the patient had no further CT or PET/CT follow-up at our institution.
