Dilated Rete Testis

Dilatation of the rete testes is a benign condition that is most commonly seen in older men (older that 60) and is commonly associated with epididymal abnormalities (e.g., spermatocele).

On ultrasound, there are multiple, small, cystic tubular structures within the rete testis. On MRI, there are serpiginous tubular structures in the rete testis that are hypointense on T1-weighted images, hyperintense on T2-weighted images, and don't enhance.
