Testicular adrenal rests


Adrenal inclusions within testes are great mimics of testicular tumors.

However, helpful clues that may help to be confident in adrenal rests are:

  • known history of congenital adrenal hyperplasia
  • bilateral and confluent nodules
  • next to testicular hilum
  • round borders, attenuating echoes
  • no calcifications, non-hypervascular on color Doppler

It is worth noting that MRI, in this case, has no proven diagnostic value. US remains the gold standard.
