A 50 year-old man visited our hospital due to left lower limb pain and numbness, urinary retention and lower abdominal pain. Contrast-enhanced CT and MRI showed a large retroperitoneal multilocular cystic mass with solid component in the pelvis cavity measuring 150 mm in size. This tumor displaced the bladder, prostate and rectum to the right side. Left hydroureter was also shown. The cystic disease originated from prostate or seminal vesicle is suspicious, however, accurate pre-operative diagnosis is unclear. He underwent resection of the tumor. Histologically, the tumor cystic wall was composed of epithelial cells showed positive immunohistochemical staining of the epithelial prostatic specific antigen, the final pathological diagnosis was prostatic cystadenoma (Rinsho Hinyokika 75: 157-16 1 2021).
