  TUBULAR ECTASIA OF RETE TESTES:                           case courtesy Dr. Ravi Kadasne, UAE--

Rete testes tubular ectasia

Rete testes tubular ectasia refers to small cystic structures appearing in the mediastinum. Common associations are intratesticular cysts and spermatoceles. This type of ectasia should not be palpable. Although most commonly bilateral, unilateral instances occur. Also, this generally occurs in older patients. This appearance and finding are pathognomonic, and further evaluation is not necessary.

Radiologic Overview of the Diagnosis: Ultrasound is an effective way to exam the testes. Multiple tiny cystic structures or tubule-like structures are seen that may enlarge the mediastinum of the testicle.

A CASE OF POLYORCHIDISM:

  This is a 26 yr. old male patient who complained of a painless swelling in theleft scrotum since a long time.

Ultrasound revealed a solid, well defined, non calcific, well-encapsulated

mass of the SAME ECHOTEXTURE as the testes. It measured almost

2 cms. in size., and located at the lower pole of left testes.

These findings are highly suggestive of supernummerary testes

or polyorchidism. The other possibilities are bilobate testes,

lipoma, fibroma and neurofibroma.

Polyorchidism is a rare anomaly with about 70 reported in literature.
