Tubular Ectasia of the Rete Testis (TERT)
Tubular ectasia of the rete testis (TERT) is a benign cystic lesion of the testis with dilatation of rete testis tubules (Dieckmann et al., 2010).
Etiology of Tubular Ectasia of the Rete Testis
TERT probably results from epididymal obstruction, often together with spermatoceles. Vascular or hormonal causes are also associated with TERT.
Diagnosis of TERT
Ultrasound imaging of the testes: the size of the anechoic cysts in the area of the rete testis is variable but often less than 3 mm. The cystic area has a diameter of 1–3 cm, and three-quarters of all cases present with a spermatocele [fig. Ultrasound imaging of TERT].
Cystic teratoma, cystic testicular dysplasia, simple testicular cyst, epidermoid cyst.
Treatment of Tubular Ectasia of the Rete Testis (TERT)
Treatment of TERT is not necessary. Sometimes, symptoms lead to spermatocele resection. Unclear cases with suspicion of testicular tumor necessitate inguinal approach to the testis and biopsy of the lesion.
