title: Pneumocephalus associated with a frontoethmoidal osteoma.
abstract: A 51-year-old man complained of a headache of 2-months duration. Computerized tomography revealed pneumocephalus and an osteoma at the confluence of the frontal and ethmoid sinuses on the right. Craniotomy confirmed an osteoma with a spur as the cause of the pneumocephalus.
