[A rare cause of exophthalmos, hydatid cyst of the orbit]. / Une cause rare d'exophtalmie, le kyste hydatique de l'orbite.

INTRODUCTION: The orbital hydatid cyst is a rare (1 to 2%) localization of the Echinococcus granulosus parasite. OBSERVATIONS: An intra-orbital localization of hydatidosis was revealed in two patients by the occurrence of unilateral exophthalmia.
