Figure 3.

An 84-year-old male with penile cancer. Axial T2*-weighted MR image shows an enlarged lymph node in the left inguinal region (arrow) (A). Axial T2*-weighted MR image obtained 24 hours after intravenous injection of ferumoxytol shows persistently high signal intensity within the left inguinal adenopathy (arrow) (B) which suggests metastatic involvement of penile cancer. Axial 18F-FDG-PET/CT image shows tracer uptake within the left inguinal adenopathy which confirms presence of metastasis (arrow) (C).
