Abstract

Mostly Schwannomas are concentrated in relation to the Acoustic or Cochlear division of the Eighth Cranial nerve which is the Vestibulocochlear nerve. These lesions are usually benign. We present a rarer location of Schwannoma lying in relation to the Foramen Magnum which is not a common location for such masses. The Anatomical relations determine the Presentation of the Tumors and in this case the rare presentation was to the surprise of ours.
