[Unilateral pseudotumoral exophthalmos in ethmoid-sphenoid-maxillary mucocele].

The authors present a case of ethmo-spheno-maxillary mucocele revealed by the appearance of a giant unilateral exophthalmia with an important decrease of visual acuity and spectacular regression of symptomatology after surgical excision. We must note the initial location near the tear ductus, the slow progression (12 years) with a false aspect of chronic dacryocystitis.
