Paranasal sinus mucocele is the cystic formation lined by inflammatory changed mucoperiosteum. This is slow-growing pathology with a tendency to bone erosion. The symptoms are dependent on the direction of the penetration, and are as follows: increasing headaches, deformations of frontal or orbital region, ophthalmic manifestations such as lacrimation, decreased visual acuity, exophthalmos, ocular movement limitation, diplopia. The most common location of the mucocele is fronto-ethmoid region. The most useful diagnostic tests are a magnetic resonance imaging (MRI) and a computed tomography (CT) which show the progress of the disease and bone destructions. Surgery is the only method of treatment (external approach or FESS). This paper reports the case of a 74-year-old woman with ethmoid mucocele penetrating into the orbit, frontal sinus and anterior cranial fossa with compression of frontal lobe of the brain. The patient underwent CT and MRI and was treated with endoscopic intranasal marsupialization of the cyst. There are no clinical signs of disease recurrence 7 months after surgery. The endoscopic surgical management in treatment of sinus mucocele is a good alternative to the operation from external approach because of its low invasiveness, low complication risk, rapid healing and good therapeutic effects.
