Case Discussion

Tubular ectasia of the rete testes is a benign condition that is usually found bilaterally. It is commonly asymmetric as in this case and rarely unilateral. Absence of blood flow and its characteristic appearance and location is diagnostic. Tubular ectasia is frequently associated with spermatoceles and testicular cysts.
