Fig. 1A.30-year-old man with urinary retention. CT scan shows large
complex cystic mass in expected location of prostate gland. Mass displaces
bladder (arrowhead) anteriorly and sigmoid colon (arrow)
laterally.
Fig. 1B.30-year-old man with urinary retention. Endorectal sonogram
reveals multiseptated cystic mass (arrow) arising from normal
prostatic tissue. Bladder (arrowhead) can be seen anteriorly.
Fig. 2A.41-year-old man with acute urinary retention. CT scan shows
large multiloculated cystic mass arising from prostate gland, which is
displaced to right side. Bladder (arrow) is filled with contrast
material, and Foley catheter (arrowhead) is seen in prostatic
urethra.
Fig. 2B.41-year-old man with acute urinary retention. CT scan
obtained 1 year after surgical resection of mass shows recurrence of loculated
cysts in lower pelvis. Foley catheter (arrow) was placed to alleviate
urinary obstruction.
Fig. 2C.41-year-old man with acute urinary retention. Sagittal
T2-weighted MR image obtained at same time as B reveals recurrent large
multiloculated cystic mass that displaces bladder (arrow)
anteriorly.
