Reason: trigeminal neuralgia; referred for radiosurgery; please obtain for treatment planning purposes History: trigeminal neuralgia The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the SWI images.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.This is a limited examination for the purpose of treatment planning for trigeminal neuralgia. No obvious intracranial mass lesion is appreciated.2.Periventricular and subcortical white matter changes of a mild degree are nonspecific. At this age they are most likely vascular related.
