Abstract

Tubular ectasia of the rete testis is a benign condition characterized by cystic dilatation of the rete testis, usually resulting from partial or complete obstruction of the efferent ducts. Bilateral involvement is uncommon and may simulate more serious testicular pathology. We report the case of a 62-year-old man presenting with chronic scrotal enlargement. Scrotal ultrasonography demonstrated bilateral tubular ectasia of the rete testis associated with a right hydrocele. Recognition of the characteristic sonographic appearance allowed a confident diagnosis and avoided unnecessary invasive procedures.
