Cystadenoma of the rete testis

Cystadenoma of the rete testis is a rare cystic testicular tumor. It does not have specific imaging features, but may be suggested in the differential of a large multiloculated cystic tumor involving the testicle. It cannot be radiologically differentiated from cystadenocarcinoma.

Reported in patients aged 26-66 years old. No known risk factors.

Histologically, some cystadenoma variants may resemble Sertoli cells, and has been termed "sertoliform cystadenoma".

  • multilocular cystic tumor
  • may extend from the intratesticular mediastinum testis into the extratesticular space
  • solid nodular components are possible, but uncommon

Surgical excision is usually the treatment of choice. Recurrence is possible, so post surgical follow up is usually necessary.
