RESUMO
ABSTRACT: 18F-PSMA is a promising tracer for both staging and detection of biochemical recurrence in prostate cancer. PSMA is also expressed in the benign pathological conditions. We report a case of 81-year-old man with a known case of prostate cancer who underwent 18F-PSMA for restaging. 18F-PSMA PET/CT shows intense tracer uptake in the frontal bone appearing like an "Iron Man" sign. Corresponding noncontrast CT images, pagetoid changes with thickened cortex, mixed lytic/sclerotic mottled pattern. It is important to recognize 18F-PSMA expression in the benign nonprostatic pathologies to avoid false interpretation.
