Zystadenom des Nebenhodens

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:

• epididymal cysts
• spermatoceles
• teratomas 
• adenomatoid tumors of the scrotum

Practical points

Patients with bilateral papillary cystadenomas of the epididymis should be considered for vHL screening .
