MRI Brain Report Explanation - Mr. Sunil Kumar (52 years, Male)

What the MRI Was Looking For

Finding 1 - The Main Finding (Most Important)

"Altered signal intensity appearing hyperintense on T2 and TIRM images seen involving the pons, medulla, cerebral peduncle and bilateral cerebellar hemisphere with associated volume loss/atrophy and prominence of the folia... Findings are likely sequelae to previous insult."

• The pons, medulla (both parts of the brainstem), cerebral peduncle (connection between brain and brainstem), and both cerebellar hemispheres (back of the brain that controls balance/coordination) are showing abnormal bright signals on T2 and TIRM (also called FLAIR) sequences.
• These areas also show shrinkage/atrophy - meaning tissue has been lost.
• "Prominence of the folia" means the folds of the cerebellum have become more visible because the tissue between them has shrunk.
• "Sequelae to previous insult" = these are the permanent aftereffects of something that happened to the brain in the past - most likely a prior stroke or ischemic event in the posterior (back) circulation of the brain (the vertebrobasilar territory).

Finding 2 - Enlarged Spaces Around the Brain

"Prominence of the extra-axial spaces, sulci, system and 4th ventricle in the region/posterior compartment."

• The spaces outside the brain tissue (extra-axial spaces), the grooves on the brain surface (sulci), and the 4th ventricle (fluid space in the brainstem/posterior fossa) are all larger than normal.
• This is consistent with cerebral and cerebellar atrophy - the brain has shrunk somewhat, so the spaces around it have expanded to fill the void.
• The 4th ventricle enlargement in the posterior compartment is directly related to the cerebellar volume loss above.

Finding 3 - Virchow-Robin Spaces

"Prominent Virchow-Robin spaces seen in bilateral gangliocapsular region."

• Virchow-Robin spaces are normal tiny fluid-filled tunnels that follow blood vessels into the brain.
• When they become enlarged/prominent, they show up on MRI as small bright spots.
• They are most commonly seen in the basal ganglia region (gangliocapsular area = area around the internal capsule and basal ganglia), which is exactly where this report mentions them - as confirmed by Bradley and Daroff's Neurology in Clinical Practice, which describes them as "most often seen in the basal ganglia region (type I Virchow-Robin spaces)" and notes they can be confused with small infarcts.
• Prominent Virchow-Robin spaces are generally considered a benign, age-related finding, though they can be associated with hypertension and small vessel disease.

Finding 4 - Normal Findings (Reassuring)

"No evidence of abnormal blooming on SWI." The flowvoids of the bilateral major cerebral arteries are maintained.*

• No blooming on SWI = no evidence of old bleeds, microhemorrhages, or blood products.
• Flowvoids maintained = the major brain arteries (internal carotids, middle cerebral, basilar, etc.) are showing normal blood flow on MRI. No large vessel occlusion.

What Should Be Done Next

1. Contrast MRI of the brain - to rule out any active enhancement (which would suggest ongoing inflammation, demyelination, or tumor rather than pure old stroke scar).
2. Neurologist consultation - this pattern of posterior fossa damage requires detailed history: Did Sunil Kumar have any episode of sudden-onset giddiness, double vision, difficulty swallowing, or weakness in the past? These would be classic brainstem stroke symptoms.
3. Vascular risk factor assessment:
   • Blood pressure control (hypertension is a major cause of posterior circulation stroke)
   • Blood sugar (diabetes check)
   • Lipid profile (cholesterol)
   • ECG/Holter (to check for atrial fibrillation, a cause of embolic stroke)
   • Carotid/vertebral Doppler ultrasound or MR angiography of neck vessels
4. Antiplatelet therapy (e.g., aspirin/clopidogrel) if not already prescribed - standard secondary stroke prevention, but this must be decided by the treating physician.
5. Physiotherapy/rehabilitation if there are residual deficits from the original event.
