Figure 16 (A-D): Hypoglossal nerve schwannoma. Axial B-FFE (A) and T2-weighted (B) images show well-defined heterointense mass in right hypoglossal canal arising from hypoglossal nerve and extending into the cerebello-medullary cistern. Post-contrast axial T1-weighted image (C) shows intense enhancement in the mass. The right half of the tongue shows fatty replacement of the intrinsic muscles and appears hyperintense on T1-weighted image (D). No biopsy was done. The patient underwent cyberknife radiosurgery
