Ultrasound image showing tubular ectasia of the rete testis as an incidental finding in an 81 year old male. Rete tubular ectasia, also known as cystic transformation of rete testis [1] is a benign condition, usually found in older men, involving numerous small, tubular cystic structures within the rete testis.
The rete testis (/ ˈ r iː t i ˈ t ɛ s t ɪ s / REE-tee TES-tis; pl.: retia testes) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts. It is the homologue of the rete ovarii in females. [1]

The lobules are conical in shape, the base being directed toward the circumference of the organ, the apex toward the mediastinum testis. Each lobule is contained in one of the intervals between the fibrous septa which extend between the mediastinum testis and the tunica albuginea , and consists of from one to three, or more, minute convoluted ...
