Late Recurrence of Brain and Orbital Hydatid Cyst: A Case Report and Literature Review

Background: Hydatidosis is a zoonotic disease endemic in some parts of the world including Morocco. The cyst is commonly encountered in the liver, lungs, heart muscle and central nervous system. Case Description: A 16-year-old-male with a history of intra orbital hydatid cyst presented with a progressive worsening of the vision on the right eye as well as proptosis and headache. Indeed, he had been operated 13 years ago for a right intra-orbital cyst and received Albendazole for an unknown duration. The MRI showed an intra-axial cystic mass extending from the right temporal lobe to the eyeball through the superior orbital fissure, suggesting a hydatid cyst. The patient benefited from total excision of the cyst despite a perioperative rupture. Conclusion: Hydatid cyst can recur even many years after the first episode. Relapse is common, especially if a rupture occurred during previous surgery. Medical treatment with a long follow-up is recommended.
