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.
Tubularectasia of the testis is a benign condition, also know as cystic transformation of the retetestis, and results from dilatation of the efferent tubules, which causes ectasia and cystic transformation.
Although the origin of the ectasia is vague, it probably represents changes secondary to obstruction of the tubules following infection or trauma.
Intratesticular varicocele is a rare entity, which can have a similar appearance to tubularectasia, but it increases in size on the Valsalva manoeuvre and shows blood flow.
