abstract ={Background: Primary retroperitoneal serous cystadenomas (PRSCs) are extremely rare, and their
pathogenesis is not well understood. Differentiating these tumors from other cystic or tumorigenic lesions
can be challenging given the unusual retroperitoneal location and varied symptomatology.
Case Presentation: An 83-year-old female was evaluated for vaginal prolapse symptoms, fecal
incontinence, and intermittent mixed urinary incontinence symptoms. Magnetic resonance imaging showed
a large space-occupying cystic structure closely associated with the rectum. After exploratory laparotomy
with excision of the retroperitoneal mass, biopsy showed a simple cyst filled with serous fluid and lined by
a single layer of cuboidal epithelial cells consistent with serous cystadenoma. On follow up visit, she
reported improvement in stress urinary incontinence, but continued to have difficulty with urinary and bowel
urge incontinence.
Conclusion: PRSCs should be considered during evaluation of retroperitoneal space-occupying lesions
despite the rarity of serous cystadenomas being found in this location. The pathophysiology of how PRSCs
arise is still not well understood but establishing better techniques to distinguish these lesions from other
cystic and tumorigenic lesions should be investigated.}
