Case:
A 72-year-old man presented with left exophthalmia, impaired visual acuity and ocular pain. CT revealed a posterolateral homogeneous unilocular cyst in the left orbital cavity. Ultrasound showed a 38 x 17 mm purely cystic retro-ocular thin lined mass. Hydatid serologic tests were positive. The cyst was completely enucleated, after irrigation with hypertonic saline solution. The diagnosis was confirmed histologically.
Discussion:
The orbital hydatic cyst is a rare pathology in Western countries but remains relatively frequent in North-African countries. It can be observed in urban centers a high percentage of immigrant population. It is thus necessary to keep this pathology in mind when confronted to an intra-orbital cystic formation and to avoid its rupture.
