Papillary cystadenoma of the epididymis

Papillary cystadenomas of the epididymis are the second most common benign tumours of the epididymis after adenomatoid tumours. They are more common in young men. Approximately 30% of the patients have von Hippel Lindau disease and approximately 10% to 40% of patients with von Hippel-Lindau disease have papillary cystadenoma.

Papillary cystadenomas are usually asymptomatic.

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.
