Abstract: Hydatid disease, a zoonotic infection, is a parasitic affliction caused by Echinococcus species. Hydatid cysts by far are usually located in the liver and lung. Retro rectal hydatid is an exceedingly rare occurrence, in comparison. In this case report, we present the case of a 48-year-old male who initially presented to us as benign fistula in ano, and on evaluation, was found to have a retro rectalcystic mass lesion. Magnetic resonance imaging of the pelvis revealed a left postero-pararectal unilocular cyst measuring 8 ?7.8 cm with Type I fistula in ano. The patient successfully underwent enucleation of the cyst, which on histopathological examination proved to be cystic hydatosis. This demonstrates the sinister ubiquity of human hydatid disease in the differential diagnosis of any cystic mass in any anatomic location of human body, and more so in endemic regions.
