ORBITAL HYDATID CYSTS - REPORT OF 4 CASES

Hydatid cysts of central nervous system are rare and comprise only 2% to 3% of all hydatid cysts reported. Orbital localization is very unco mmon and has been reported less than 1% of all hydatid diseases. The p rimary treatment of hydatid disease is surgical. The most important co mplication of the surgical treatment is secondary hydatidosis due to s pillage of the cyst contents. Because of the difficulties of the orbit al localization, total extirpation of the cysts without rupture is alm ost impossible. Preventing spontaneous rupture of the cysts during sur gery and postoperative antihelmintic treatment should be taken into co nsideration in these cases. This study includes four cases who underwe nt surgery for orbital hydatid cysts. Radiological characteristics, op erative technique and postoperative medical therapy are discussed.
