papillary cystadenoma of the epididymis
Papillary cystadenomas of the epididymis are the second most common benign tumors of the epididymis after adenomatoid tumors and are common in patients with von Hippel-Lindau disease (vHL).
Clinical presentation
Papillary cystadenomas are usually asymptomatic.
Epidemiology
They are more common in young men (20-40 years) . Approximately 30% of patients have vHL and ~35% (range 10-60%) of patients with vHL have papillary cystadenoma(s) .
Radiographic features
Lesions are usually arising from the head of the epididymis and can present as a cystic lesion with a thick wall and several peripheral solid nodules with increased vascularity, partially or completely cystic or solid lesion and measuring up to 3 cm in diameter .
Differential diagnosis
Considerations include:
Practical points
Patients with bilateral papillary cystadenomas of the epididymis should be considered for vHL screening .
