Frontal sinus osteoma complicated with intracranial inflammatory polyp: a case report and review of the literature.
BACKGROUND
Osteomas of the paranasal sinuses rarely cause intracranial manifestations. A neurological symptom may be the first sign of a previously unrecognized osteoma.


METHODS
A 28-year-old male was referred with one episode of witnessed tonic-clonic seizure and loss of consciousness. Radiologic examination revealed a calcific mass in the frontal sinus and a cystic structure was detected in the posterior component of the lesion. The patient underwent a combined nasal endoscopic approach and a bilateral frontal osteoplastic craniotomy. The ossifying tumoral tissue and the polypoid soft tissue mass were removed. The histo-pathologic diagnosis of the hard, bony tumor was consistent with an osteoma and the polypoid soft tissue was an inflammatory polyp.


CONCLUSIONS
This case report illustrates a rare and life threatening complication of a frontal sinus osteoma with an intracranial extension of an inflammatory polyp.
