Total Resection of Intraorbital Hydatid Cyst by Using Lynch Approach: A Case Report

Abstract

Hydatidosis is a chronic zoonotic infection of humans caused by the infestation of larvae of the tapeworm Echinococcus granulosus. All parts of the body can be infected, especially the liver and lungs. Intraorbital hydatid cyst (HC) is a rare entity and accounts for less than 1% of all hydatid cysts. Total resection of the cyst can be very challenging due to the limited area within the orbit and the severe adhesion to adjacent structures. Several surgical approaches have been described in the literature depending on the size and location of the cyst. We reported a case of retrobulbar HC in a 10-year-old boy which was completely resected using the Lynch approach. Our case should be the second reported case from Syria and the first case that used the Lynch approach in the literature.
