Overview
Adenomatoid tumor is a mesothelial tumor. It generally presents in the genital tract, in regions such as the testis and epididymis.However, it also has been found in the pancreas.
Pathophysiology
- Adenomatoid tumors are benign, solid extratesticular lesions that can originate from the epididymis, tunica vaginalis, or spermatic cord.[1][2][3]
- They are the most common tumor of the epididymis.[4][5]
- They occur more often in the lower pole than in the upper pole by a ratio of 4:1.[6][7][8]
- Usually an incidental finding, adenomatoid tumors manifest as a painless scrotal mass, with the majority diagnosed in patients aged 20–50 years.[9][10][11]
- 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.[12][13][14][15]
Diagnosis
Ultrasound findings
- On an ultrasound, they appear as a solid extratesticular mass with variable echogenicity.[16]
MRI
- Commonly, MRI demonstrates low signal intensity relative to the testicular parenchyma on T2-weighted images.
- MRI can aid in determining the paratesticular origin of the lesion.
- Adenomatoid tumors enhance after administration of gadolinium contrast material.
