PROTOCOL:
T1W – Sagittal & axial scans
T2W – Axial & coronal scans
FLAIR – Axial scans
FINDINGS:
-Evidence of Globi palledi hyper intensities is shown on T2, Flair and diffusion weighted images in addition to faint hyper intensities noted in both insulae and centrum semi ovale.
-After contrast injection; no definite abnormal enhancement could be noted.
-No hyper intense signal could be seen in both Globi palledi on T1; suggestive of absence of hemorrhage.
-The rest of the brain Parenchyma shows normal grey white matter differentiation and signal intensities. No focal mass lesion is seen.
-Lateral and third ventricles are normal in size and position. Septum is in midline. There is no midline shift.
-Basal cisterns, cortical sulci and gyri are normal in appearance.
-Corpus callosum shows normal MR morphology.
-Brain stem and cerebellum show normal signal intensities.
-Fourth ventricle is normal in size and is midline in position.
OPINION:
• Picture is suggestive of Co monoxide poisoning resulting in anoxic ischemic encephalopathy.
• Presence of bilateral symmetrical affection of Globi palledi on diffusion weighted images suggests Chronic stage of Co monoxide poisoning.
• Other causes of the previously described MR picture are Japanese encephalitis or Wilson disease.
• For clinical correlation.
