Symmetrical areas of altered signal intensity in bilateral globi pallidi, posterior limb of internal capsule
, subthalamic nuclei and cerebral peduncle, hyperintense on T1/FLAIR, isohypointense on T2W showing no restriction of diffusion.
The MRI films were reviewed and revealed well defined abnormal signal intensity areas in basal ganglia and posterior limb of internal capsule
. Lesions appeared hypo-intense on T1 and hyper-intense on T2 and FLAIR (fig-1).
After doing MRI, ischaemic injury has to be appreciated by detecting abnormal signal intensities in the following areas Subcortical white matter and (+/_) cortex, Posterior Limb of Internal Capsule
(PLIC), Perirolandic White Matter (PRWM), Periventricular White Matter (PVWM), basal ganglia, thalami and brainstem.
