Rete tubular ectasia is a benign condition, usually found in older men, involving numerous small tubular cystic structures within the rete testis.

Epidemiology

Obstruction may be the common underlying factor.

Diagnosis

The condition can be detected with sonography. It is commonly associated with epididymal abnormalities, such as spermatocele, epididymal cyst, and epididymitis. The condition shares a common location with cystic dysplasia of the testis and intratesticular cysts.

Treatment

Typically none is required.
