Diagnosis: Demyelinating disease of central nervous system, unspecifiedClinical question: CNS demyelinating disease re evaluateSigns and Symptoms: None The CSF spaces are appropriate for the patient's stated age with no midline shift. There is redemonstration of signal hyperintensity along the lateral aspect of the right precentral gyrus predominantly involving white matter in the region measuring approximately 1 cm x 0.5 cm in axial dimensions is associated with a focus of susceptibility effect. There is no abnormal enhancement associated with this. The patient is status post burr hole placement in the adjacent overlying calvarium.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.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.The MRI of the brain is stable compared to the prior exam. There is a small lesion in the right precentral gyrus which is stable compared to the prior exam.2.Periventricular and subcortical white matter changes of a mild degree are nonspecific. At this age they are most likely vascular related.
