Abstract

We present an extremely infrequent case of a patient suffering from visual acuity loss due to optic nerve compression caused by sphenoid mucocele secondary to a fibrous dysplasia. We present a 29-year-old man reporting a gradual loss of the visual acuity in the left eye during the last five days. The complete study, including MRI, revealed an extended fibrous dysplasia involving the right sphenoid and associated to a retention mucocele causing compression to the left optic nerve on its cisternal trajectory. The patient underwent a left transnasal endoscopic sphenoidotomy with abundant drainage of the mucocele by marsupialization and creation of a new drainage pathway and preservation of the epithelium. One month later, ophthalmologic examination revealed an important improvement on the visual acuity of his left eye. Fibrous dysplasia accounts for 2% to 5% of all bone tumors. Mucoceles are benign masses that may provoke serious complications due to anatomical relationships when they grow. The apparition of both conditions associated is very rare. Acknowledging the connection between the two conditions to get an accurate diagnosis is crucial. An early surgical procedure improves the functional prognosis of the patient.
