Introduction:

Hydatid disease, also knowns as echinococcosis, is an uncommon zoonosis frequently caused by the Echinococcus parasite, class cestodes, and phylum flatworms. Four species have been described, the ones with human medical relevance are multilocularis echuinococcus, vogeli echinococcus y granulosus echinococcus, last one being responsible for 95% of the human hydatidosis cases reported. They frequently affect the abdominal cavity, are located in the liver, spleen, kidney, and muscle, and rarely in the retroperitoneum.

Clinical case:

it is about a male patient, 30 years old, with symptoms for 3 years, feeling abdominal pain in right hemi-abdomen, ambulation disturbance, and constipation; after imaging tests is confirmed pathology compatible with Hydatid disease in right hemi-abdomen, Antiparasitic medical treatment was started for a month and then open surgical resolution was performed by resection of the right retroperitoneal cyst, with good results.

Conclusion:

This report owes its importance to the limited documented cases in the country, especially in the eastern region. It is also relevant because of the little-known special surgical technique used and the constant influx of foreigners in the country with unusual epidemiological pathologies that require treatment during their stay.
