Abstract: Sinusitis are entities that rarely risks patient's life, but they can eventually present orbital, bony or even intracranial complications. Relating to these aspects, sphenoidal sinusitis seems to be a very singular pathology. The sphenoid sinus, besides it rarely is the isolate site of an infeccious process, when involved seems to have complications in a great part of the patients. Early diagnosis and effective treatment should be remembered for a better control of morbidity and mortality of sphenoiditis. The authors report a case of sphenoid sinusitis with intracranial complications that had a satisfactory evolution with clinical management.
