Hypoglossal schowannoma: a case report and review of literature

Schawannomas [neuromas, neurilemmomas] are benign tumors originating from showann cells or nerve fiber sheet cells. They are solitary, encapsulated tumors usually attached to, or surrounded by a nerve. We present a case of left hypoglossal nerve schwannoma in a 19 year old man who was admitted with progressive left tongue atrophy. Schwannoma of the hypoglossal nerve usually develops in the intracranial and extracranial portion or both in the intracranial and extracranial components forming a dumbbell shape tumor .The peripheral hypoglossal schwannomas are extremely rare
