Mucoceles of the sphenoid sinus: neuro-ophthalmologic manifestations.

Seven examples of mucocele of the sphenoid sinus have been described. The characteristic symptoms and signs have been described, and the diagnostic neuroradiologic features have been demonstrated. The condition is not a benign one, as is demonstrated by total blindness which occurred in one patient (Case 2). A high index of suspicion for this condition with early referral for neuroradiologic diagnosis leads to proper management and treatment which is usually successful.
