Discussion of Papillary cystadenoma
- Papillary cystadenoma of the epididymis is a benign epithelial neoplasm.
- It is seen in up to 60% of men with Von Hippel–Lindau disease.
- Although the sporadic variety is usually seen in middle-aged men, it occurs earlier in patients with von Hippel–Lindau disease.
- Most are treated conservatively with serial US to monitor lesion growth.
 Imaging Findings for Papillary cystadenoma
- The sonographic appearance can be variable.
- Commonly, it will have a solid appearance with few cystic spaces.
- Alternatively, it can appear as a multiloculated cystic lesion with small papillary projections.
- In patients with von Hippel–Lindau disease, sonographic criteria for diagnosis of epididymal cystadenoma consist of
- A predominantly solid epididymal mass larger than 10 x 14 mm and
- Slow growth.
- At MR imaging, a cystic mass with septations or mural nodules can be seen. The internal architecture of the lesion can be demonstrated at gadolinium-enhanced T1-weighted imaging.
