[edit] Discussion of Dilated rete testis

  • Dilated rete testis represents dilated testicular mediastinal tubules
  • This is a benign condition thought to result from partial or complete obliteration of the efferent ducts.
  • It is often bilateral, is frequently associated with spermatocele.
  • It is more common in men over the age of 55 years.

[edit] Imaging Findings for Dilated rete testis

  • At sonography, it appears as multiple small cystic or tubular anechoic structures that replace and enlarge the mediastinum. The geographic shape, lack of mass effect, and lack of internal flow are helpful to distinguish this benign condition from a partially cystic tumor.
  • At MR imaging, the cystic dilatation or ectasia of multiple small tubules of the rete testis appears hyperintense on T2-weighted images. After administration of gadolinium contrast material, no internal enhancement is seen.
