Isolated Testicular Metastasis Diagnosed More than a Decade and a Half Post Primary Treatment for Prostate Cancer

Figure 2

(a) ⁶⁸Gallium prostate-specific membrane antigen-based PET maximum-intensity projection images demonstrating patient with a single left testicular metastasis (arrow); no other metastasis lesions were identified elsewhere. (b) ⁶⁸Gallium prostate-specific membrane antigen-based PET/CT axial fusion image demonstrating again a single uptake within the left testicle, holding a SUVmax of 9.3 mSv, consistent with metastasis. (c) Coronal image of a T2-weighted (T2W) magnetic resonance image (MRI) showing several hypointense lesions involving the left testicle (arrow), suggestive of metastasis. (d) Axial image of a T2W MRI showing again several hypointense metastatic depositions within the left testicle.
