Primary meningioma of the fallopian canal

Meningiomas are slow-growing lesions that represent approximately 20% of al l intracranial tumors and are the second most common tumor of the cerebello pontine angle. In contrast, primary extracranial meningiomas are found rela tively infrequently, and most cases have inadequate radiologic studies to d etermine if they were actually an extension from a primary intracranial sou rce. Meningiomas of the intratemporal segment of the facial nerve have also been reported, but they are exceedingly rare and their pathophysiology rem ains unclear. We report a case of a meningioma of the facial nerve in the f allopian canal of a 7-year-old girl and review pertinent literature.
