The ethmoid mucocele, resulting in the proptosis, is known a rare benign lesion. There are a number of ophthalmic manifestations of cystic lesion arising from the ethmoid sinus, which has destroyed the lamina papyracea and invaded the orbit. It is demonstrated by simple orbit X-ray and orbit CT scan. We experienced a case of a ethmoid mucocele in a 36-year-old man. which was associated with frontalgia, proptosis and transient intraocular pressure elevation and was improved after intranasal ethmoidectomy.
