Legend
Images 1 & 2: Axial T2 and proton weighted images of brain reveal hyperintense
lesion in the Rt temporoparietal region, involving both gray and white matter.
No significant mass effect on the adjacent Rt lateral ventricle is seen.
Legend
Image 3: Coronal T1 weighted image shows gyriform hyperintense area
involving mainly the cerebral cortex of the Rt parietal lobe.
Images 4 & 5: Coronal and axial post gadolinium T1 weighted images
reveal gyriform enhancement in Rt parietal and frontal regions of the brain.
Legend
Image 6: Axial T2 weighted image reveal much smaller Rt internal carotid artery
when compared with its Lt counterpart.
Image 7: Source image of the MR angiogram confirms the previous finding of small
Rt internal carotid artery on image 6.
Image 8: Maximum intensity projection image of MR angiogram demonstrates the small
internal carotid artery on Rt side and decreased flow-enhancement of the Rt middle
cerebral artery. The anterior and Rt posterior communicating arteries are not well seen.
Image 9: Axial source image from the MR angiogram shows asymmetric
flow- enhancement of the middle cerebral arteries within the sylvian fissures due to
decreased flow in the Rt MCA.
