[edit] 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.

[edit] 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.
