Fig 4. A 37-year-old woman with a cervical schwannoma. A, Axial contrast-enhanced fat-saturated T1-weighted image shows intensely enhancing well-circumscribed right-sided cervical mass. Differentiation with a paraganglioma is difficult. B, CE-MRA axial MPR image does not show the typical tumor blush in the arterial phase, which indicates that this tumor is probably not a paraganglioma. Note the anterior displacement of both the internal and external carotid arteries due to the schwannoma.
