Result: serial sections of the brain were obtained in sagittal, corneal and axial planes using t1, t2, and flair images. Small area of diffusion restriction is noted in the left perisylvian region appearing hyperintense on t2/flair. Few t2/flair hyperintense foci are seen in bilateral frontal-parietal regions-s/o chronic microangiopathic white matter ischemic changes. Rest of the brain parenchyma shows normal Mr. morphology and gray-white differentiation. The basal cisterns and superficial subarachnoid csf spaces are normal. The ventricular system is normal. The midbrain, pons and medulla are normal. The cerebellar hemispheres are normal. Visualized parts of the sella, 5th, 7th and 8th nerve complexes are grossly normal on routine brain imaging. Major flow voids are present. Bilateral maxillary sinusitis seen. Impression: Mr. reveals:- small area of diffusion restriction in the left perisylvian region appearing hyperintense on t2/flair suggestive of acute infarct. - chronic microangiopathic white matter ischemic changes in bilateral frontal-parietal regions.
