Abstract:
A 28-year-old patient was admitted to radiology department due to a painless left-sided extra scrotal lump and discomfort in the ipsilateral lower inguinal region. Scrotal ultrasound revealed an oval circumscribed soft tissue mass, located in the proximity of the distal part of spermatic cord, without visible flow at Color Doppler. Scrotal MRI depicted T2 hyperintense, T1 hypo- to isointense oval mass with diffusion restriction and no fat suppression, surrounded by T1/T2 hypointense rim, located close to the spermatic cord. Additionally, MRI revealed coma-shaped T1 iso-/T2 hypointense related to the testicle formation. Following the intravenous administration of gadolinium-based contrast agent, both previously described structures enhanced. Taking into account that malignancy could be the potential complication of polyorchidism our patient was operated and histopathology confirmed supernumerary testicle with cribriform epididymal hyperplasia.
