Intracranial hypoglossal schwannoma in a 46-year-old female: a rare case

Schwannomas are benign tumours that originate from the myelin sheath of peripheral nerves. They may be found in any part of the body. In over 90%, they present as vestibular schwannomas, arisng from 8th cranial nerve . Schwannomas that arise from the hypoglossal nerve ( 12th cranial nerve), are very rare, accounting for only 5% of all nonacoustic intracranial schwannomas. Till date, very less cases of hypoglossal schwannomas have been reported in the literature.Due to their scarcity, early diagnosis of these lesions is difficult and important for further management . Thus , Magnetic resonance imaging (MRI) is the routine imaging protcol for it. They are usually seen between the third and fifth decades of life, with no sex predilection. In the present case report, the case of a 46-year-old female presented with both eyes swelling , nystagmus , Imbalance while walking since 1month. After permorming MRI and diagnosing it ,the patient underwent excisional surgery, and pathological evaluation of the specimen confirmed the diagnosis of benign schwannoma with Antoni areas A and B.
