Can you please explain my MRI of the brain done with and without contrast please: On T2 weighted and FLAIR sequences, there are multiple subcentimeter round ovoid foci of high signal in the right frontal lobe periventricular white matter, in addition to several subcentimeter lesions in the periventricular and subcortical white matter in the left frontal lobe and the subcortical white matter in the posterior right frontal lobe. At least three subcentimeter T2 and FLAIR hyperintense foci are noted in the periventricular white matter in the right parietal lobe. No area of restricted effusion are identified. These white matter lesions do not enhance on postcontrast imaging. The corpus callosum is normal in morphology and signal. The cerebellum and brainstem are norman in strcture and signal. No evidence of cortical infarct, intracranial hemorrhage, edema, mass lesion, abnormal, enhancement, or abnormal extraaxial fluid collection. The ventricles are normal and at midline. The paranasal sinuses and the arterial flow voids are patent. No chiari malformation.
IMPRESSION:
Multiple subcentimeter T2 and FLAIR hyperintense white matter lesions are noted in the bilateral frontal lobes and in the right parietal lobe, although are more numerous in the right frontal lobe periventricular white matter. These white matter lesions are nonspecific in appearance and do not enhance on postcontrast imaging. Differential considerations include both mild chronic small vessel ischemic change and myelinating disease such as multiple sclerosis. However, these lesions cannot be further defined. No evidence of acute infarct, cortical infarct, intracranial hemorrhage or mass. No evidence of acute intracranial abnormality.
Thank you
