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.
