Meningiomas of the jugular foramen.

Meningiomas of the jugular foramen manifest the same signs and symptoms as glomus jugulare tumors. They arise from arachnoid cells lining the jugular bulb and grow slowly, infiltrating the temporal bone and posterior fossa. These lesions, however, are more clinically treacherous than glomus tumors. Meningiomas infiltrate surrounding bone and nerve tissue and require wide margins of resection to prevent recurrence. Eight of these lesions have been managed in the past 5 years at the House Ear Clinic using modern imaging and skull base techniques. Two have recurred after "total" microsurgical removal. Presentation, radiologic evaluation, and management guidelines are reviewed.
