[A rare cause of exophthalmos, hydatid cyst of the orbit].
BACKGROUND
The orbital hydatid cyst is a rare (1 to 2%) localization of the Echinococcus granulosus parasite.


METHODS
An intra-orbital localization of hydatidosis was revealed in two patients by the occurrence of unilateral exophthalmia. After tumoral resection the diagnosis was confirmed by histological examination.


CONCLUSIONS
The principle clinical sign of an orbital hydatid cyst is exophthalmia. Imaging is essential for pre-operative diagnosis. Serology is insufficient and treatment is surgical.
