Hydatid disease of the urogenital system,;especially seminal vesicles
and prostate, or retroperitoneum is a very rare condition. Secondary d
issemination of seminal vesicles has not been described before. We des
cribe the transrectal ultrasonography (TRUS), CT and MRI findings of a
secondary solitary hydatid cyst of the left seminal vesicle, in a pat
ient with disseminated hydatid disease involving all abdominal organs
except for right kidney. We obtained typical findings of hydatid cyst
at all modalities.
