Eleven scrotal sonographic examinations showing a spectrum of findings
within the mediastinum testis were collected over a 2 year period. Each
case showed numerous small tubular or rounded anechoic structures within
the mediastinum testis; often, the findings mimicked a hypoechoic mass.
Findings were bilateral in eight of ten patients; one additional patient
had only one testis because of orchiectomy. All patients had an associated
extratesticular finding, in most cases a spermatocele. Tubular ectasia
shares several features with testicular cysts and mechanisms of formation
are postulated to be similar to those previously proposed for testicular
cysts. Recognizing tubular ectasia is important to avoid unnecessary
concern and potential surgery.
