Can someone tell me what this MRI examination of the head means, please?

MRI examination of the head was performed on sagittal and traverse planes. Images were obtained prior to and following Gadolinium enhancement. MRI examination shows asymmetrical enlargement of the right lateral ventricle. Extensive periventricular white matter demyelination is noted on the right side. There is relative sparring of the occipital lobe white matter and medial aspect of the anterior lobe white matter. No evidence of positive mass effect is seen. Also, post-Gadolinium study shows no evidence of abnormal enhancement. Findings seen on this examination may be related to chronic ischemic change of the right parietal white matter with central atrophy. Finding may be related to chronic ischemic change of the right middle cerebral artery distribution. The presence of significant right carotid artery stenosis may be present. Correlation with duplex carotid ultrsound examination may be helpful. The remainder of the cerebral parenchyma is entirely unremarkable. Area of the brain stem and cervicomedullary junction are within normal limits. Mucosal thickenings are seen at the left maxillary sinus with air fluid level highly suggestive of sinusitis. MSK;w Impression: Asymmetric enlargement of the right lateral ventricle is noted with extensive periventricular white matter demyelination. This may be related to multiple old periventricular white matter infarct or chronic ischemic changes. No evidence of mass lesion or neoplastic process is noted. Also, no evidence of Gadolinium enhancement is seen. Further investigation with duplex carotid ultrasound examination is recommended to rule out the presence of significant right internal carotid artery stenosis. Evidence of sinusitis is seen in the region of the left maxillary sinus. Small retention cyst is also noted at the left maxillary sinus.

It's best to discuss your specific findings with your clinical provider.
