Abstract

Neurilemmomas is benign tumor originating from all kinds of cranial nerve except optic nerve and olfactory nerve, spinal nerve root and peripheral nerve. It superficially resembles neoplasm of fibroblastic origin, but has distinctive histological pattern and arise from the neuroectodermal sheath of schwann. Approximately 25% to 40% of all neurilemmomas are found in the neural structure of the head and neck. The tumor mostly develops in the acoustic nerve and there are several reports of neurilemmonas originating form tongue, pharynx, lip, larynx and palate etc. However, reports of Neurilemmoma originating from cervical vagus nerve have been extremely rare. We experienced two cases neurilemmoma of cervical vagus nerve that were treated with different surgical methods. In the first case, the tumor was extirpated by sacrificing the nerve trunk and in second case, it was enucleated by preserving the neural pathway using the microsurgical technique.
