HYDATID CYST OF THE ORBIT
AbstractHydatid cyst is the larval stage of dog tapeworm, Echinococcus Granulosis. Human infectionoccurs from ingestion of water and green vegetable contaminated with dog faeces and by handlinginfected dogs and ungulates. Although hydatid cyst has been reported to develop in any organ of thebody but 90% of the disease occurs in the liver and lungs. Other organs such as brain, bone, andrarely orbit and soft tissue may be involved. Intra-orbital hydatid cyst gradually enlarges causingprogressive proptosis, disk oedema, diplopia, exposure keratitis and if untreated to irreversiblevisual loss. Pre-operative diagnosis in spite of host of available diagnostic facilities is not alwaysconformity. The present case offered similar diagnostic dilemma. Surgical resection of the cyst isthe treatment of choice with the post-operative course of Mebendazole.
