title: Fibrous dysplasia of the sphenoid sinus and skull base presents in an adult with localized temporal headache.
abstract: Fibrous dysplasia (FD) of the sphenoidal sinus is a rare disease, especially during adulthood. We report a case of FD of the right sphenoidal sinus in an adult male patient who presented with nonspecific symptoms limited to headache localized to the right temporal area and to the inferior orbital rim of both sides. Magnetic resonance imaging revealed a dense mass that occupied the entire right sphenoidal sinus and skull base with typical ground-glass opacification and bony sclerosis of the whole sphenoidal wall. The diagnosis of FD was confirmed on pathological examination of a biopsy taken through sphenotomy. The patient underwent a subcranial craniotomy for tumor resection. After more than 4 years of follow-up, the patient was disease-free. On the basis of these clinical features, it is important to consider sphenoidal FD in both young and adult patients complaining of an unexplained headache, because it may present unusually with headache localized to the temporal region or the inferior orbital rim.
