\s=b\A 68-year-old man had memory lapse, character change, and unsteady gait. Skull films disclosed a spontaneous pneumocephalus with air in both ventricles. A dense, bony lesion in the right ethmoid area was thought to be an osteoma, a not infrequent cause of dural erosion. The bony lesion, however, proved to be an osteoid reaction around a primary neurilemoma. Neurilemomas arising in the paranasal sinuses are uncommon tumors and, to the best of our knowledge, this is the first reported case of a patient with a neurilemoma who had pneumocephalus. The lesion was excised through a Lynch approach, and the patient has remained free of tumor for the past two years. (Arch Otolaryngol 1983;109:417-419)
A short‐term service for those who are most severely ill, the intensive care unit provides twenty‐four‐hour nursing care and monitoring to help stabilize patients so that they can return to the day hospital for definitive treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
