Trigeminal nerve entrapment versus CNS demyelinating lesion: right facial pain. Internal Auditory Canals: A small venous structures courses along the superior and medial aspects of the root entry zone of the right trigeminal nerve. The bilateral trigeminals nerves are otherwise intact. There is no evidence of mass lesions. The bilateral cavernous sinuses and Meckel caves appear unremarkable. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There is hypertrophy of the posterior left inferior turbinate. There is cosmetic filler material in the bilateral cheeks, but not near the infraorbital foramen. There are postoperative findings related to maxillary reconstruction, with metal susceptibility artifact that obscures surrounding structures.
1. A small venous structures courses along the superior and medial aspects of the root entry zone of the right trigeminal nerve, which is nonspecific and may be indicative of a vascular loop syndrome or represent an incidental anatomical variant. Otherwise, no evidence of tumor or demyelinating lesions.2. Postoperative findings related to maxillary reconstruction and cosmetic fillers in the bilateral cheeks.MRI BRAIN WWO, MRI INT AUD CANAL WWO, 1/12/2016 8:02 PMCLINICAL INFORMATION:Trigeminal nerve entrapment versus CNS demyelinating lesion: right facial pain.TECHNIQUE: MRI BRAIN WWO, MRI INT AUD CANAL WWO CONTRAST.
