Gallium-68 prostate-specific membrane antigen positron-emission tomography computed tomography maximum intensity projection (a), fused coronal (b) and fused axial (c) images. Images showed prostate-specific membrane antigen-avid lesions in the prostate and right testis. A correlative ultrasonography of the scrotum showing a hypoechoic lesion in the right testis (d)

Focal PSMA uptake was also noticed in the right testis (SUVmax 10.4) and fifth lumbar vertebra [Figure 1]. Ultrasound of the scrotum showed a hypoechoic lesion in the right testis with internal vascularity [Figure 1].

PSA level, he was referred for 68Ga-PSMA PET/CT to look for any site of metastasis. PET/CT scan revealed PSMA-avid prostate lesion involving bilateral seminal vesicles (SUVmax 57.0), a right external iliac lymph node (size 1.0 cm x 0.9 cm, SUVmax 14.4), and focal PSMA uptake in the right testis (SUVmax 12.8) [Figure 2].

On follow-up, he again presented with raised PSA 3.0 ng/ml in February 2020. 68Ga-PSMA PET/CT revealed focal PSMA-avid (SUVmax 24.2) lesion in the left testis [Figure 3]. Ultrasound of the scrotum showed a hypoechoic lesion in the left testis [Figure 3].
