Parieto-occipital encephalomalacia in a child

 12yr old with repeated seizures.

Bilateral parietal and occipital gliotic-encephalomalacic changes are noted, almost in a symmetrical manner.

Hypoxic-Ischemic Brain Injury in a post cardiac arrest patient

Middle age patient, referred from outside hospital, was brought to the emergency due to a cardiac arrest, and was resuscitated successfully. Patient GCS score was low on the following days. MRI Brain was done later to r/o any hypoxic-ischemic insult to the brain.

 

Diffusion-Weighted MR image showed hyper intensity involving the bilateral precentral gyri and frontal eye-fields bilaterally.

Restricted diffusion was also seen in the bilateral parieto-occipital areas, in a relatively symmetrical manner.

T2 FLAIR and T2 FSE images showed symmetrical hyper intensity of the bilateral lentiform and caudate nuclei, but with no restricted diffusion.

Corresponding ADC mapping images showed hypo intensity consistent with restricted diffusion.

In SWI images no abnormal blooming artefacts were seen in the brain lesions.
