[edit] Discussion of Adenomatoid tumor

  • Adenomatoid tumors are benign, solid extratesticular lesions that can originate from the epididymis, tunica vaginalis, or spermatic cord.
  • They are the most common tumor of the epididymis
  • Occur more often in the lower pole than in the upper pole by a ratio of 4:1.
  • Usually an incidental finding, adenomatoid tumors manifest as a painless scrotal mass, with the majority diagnosed in patients aged 20–50 years.
  • They are typically unilateral and occur more frequently on the left side.
  • When they grow noninvasively into the testicular parenchyma, they can simulate intratesticular disease.

[edit] Imaging Findings for Adenomatoid tumor

  • At US, they appear as a solid extratesticular mass with variable echogenicity.
  • Commonly, MR imaging demonstrates low signal intensity relative to the testicular parenchyma on T2-weighted images.
  • MR imaging can aid in determining the paratesticular origin of the lesion.
  • Adenomatoid tumors enhance after administration of gadolinium contrast material.
