Male, 54 years old, with lancinating left facial pain that occurs 100 times per day waking the patient from sleep. Evaluate for structural lesions. Several scattered small discrete foci of T2 hyperintensity are seen within the periventricular and subcortical white matter, a nonspecific finding. More ill-defined T2 hyperintensity just above the right frontal horn is also seen.There is no restricted diffusion or significant parenchymal edema. No mass or mass effect is observed. No pathologic parenchymal or extra-axial enhancement is identified. There are no findings to suggest acute intracranial hemorrhage or any abnormal extra axial fluid collection. The ventricles are normal in size and morphology.Although not a dedicated cranial nerve examination, the trigeminal nerves as visualized show no gross abnormality. No abnormal enhancement is detected along the cisternal portions of the cranial nerves.Dedicated vascular imaging illustrates normal flow related signal within the anterior and posterior circulations. No significant vascular stenosis or occlusion is seen. No aneurysm or vascular malformation is identified. The left superior cerebellar artery and the left petrosal vein course in proximity to the cisternal left fifth cranial nerve, but this is not an atypical finding.
1.Scattered nonspecific white matter signal abnormality is seen. No acute intracranial abnormality is detected.2.Although not a dedicated cranial nerve examination, no specific abnormalities of the visualized portions of the left trigeminal nerve are seen.3.No significant vascular abnormalities are detected intracranially.
