Brain MRI Analysis - Radiological Report
Disclaimer: This is an educational analysis only. Formal diagnosis must be made by a qualified radiologist or neurologist with access to the full DICOM dataset and clinical history.
Patient Details (from screen)
- Patient: Bishan Pandey, 75 years old
- Sequences visible: T2 FSE (axial) | FLAIR (axial) | DWI (axial)
Key Radiological Findings
1. Severe White Matter Hyperintensities (Leukoaraiosis)
- FLAIR & T2: Extensive, confluent, bilateral periventricular and deep white matter hyperintensities
- This pattern is consistent with Fazekas Grade 3 small vessel ischemic disease
- Classic features of chronic cerebrovascular disease in an elderly patient
2. Ventriculomegaly (Central Atrophy)
- Bilateral lateral ventricles are significantly and symmetrically enlarged
- Indicates parenchymal volume loss - cerebral atrophy appropriate to age but likely pathological given the degree
- Must be correlated clinically to exclude Normal Pressure Hydrocephalus (NPH) - the triad of gait disturbance, cognitive decline, and urinary incontinence
3. Cortical Sulcal Widening
- Prominent sulci seen bilaterally - consistent with generalized cortical atrophy
4. DWI Findings
- The DWI sequence needs correlation with ADC maps (not fully visible) to assess for acute ischemic stroke - no obvious bright DWI restriction lesion is apparent from the displayed image, but this requires formal review
Differential Diagnosis (Most to Least Likely)
| Rank | Diagnosis | Supporting Features |
|---|---|---|
| 1 | Chronic Small Vessel Disease / Vascular Dementia | Fazekas 3 white matter changes, age 75, symmetric |
| 2 | Alzheimer's Disease + SVD overlap | Cortical + central atrophy in elderly |
| 3 | Normal Pressure Hydrocephalus | Ventriculomegaly - needs clinical triad correlation |
| 4 | Subcortical Ischemic Vascular Disease (Binswanger's) | Confluent periventricular white matter changes |
| 5 | Acute-on-chronic infarct | DWI needed for confirmation |
Clinical Correlation Recommended
- History of hypertension, diabetes, hyperlipidemia, atrial fibrillation
- Cognitive screening (MMSE/MoCA)
- Gait assessment
- Blood pressure review
- Consider neurology/neuroradiology referral for complete reporting

Here is a comprehensive summary of Binswanger's Disease drawn from multiple authoritative neurology and psychiatry textbooks.
Binswanger's Disease (Subcortical Arteriosclerotic Encephalopathy)
Gross Pathology
Below is the classic gross pathological cross-section from Kaplan & Sadock's Comprehensive Textbook of Psychiatry, demonstrating the hallmark finding - extensive subcortical white matter infarction with sparing of the overlying cortical gray matter:
Definition & Terminology
Binswanger's disease goes by several names:
- Subcortical Arteriosclerotic Encephalopathy (SAE)
- Leukoaraiosis (when referring to the imaging appearance)
- Subcortical Ischemic Vascular Dementia (SIVD)
It denotes a widespread degeneration of cerebral white matter occurring in the setting of hypertension, small vessel atherosclerosis, and multiple (often silent) strokes. - Adams and Victor's Principles of Neurology, 12th Ed.
Previously considered rare, MRI has revealed this condition is far more common than originally thought. - Kaplan & Sadock's Synopsis of Psychiatry
Pathophysiology
| Factor | Detail |
|---|---|
| Primary mechanism | Chronic ischemia of deep white matter from small arteriolar sclerosis |
| Vascular target | Small- and medium-sized cerebral vessels (arterioles) |
| Key paradox | Vessel lumens are often OPEN (patent) despite arteriolar sclerosis - Fisher, 1989 |
| White matter damage | Multiple small infarctions, gliosis, demyelination, increased water content |
| Cortex | SPARED - infarctions are subcortical |
The condition likely exists on a continuum with leukoaraiosis - many elderly individuals with white matter changes show cognitive impairment even without a formal Binswanger's diagnosis. - Adams and Victor's Principles of Neurology
Clinical Features (The Triad)
| Feature | Description |
|---|---|
| Dementia | Gradual cognitive deterioration, subcortical pattern - executive dysfunction, slowed processing |
| Pseudobulbar state | Dysarthria, dysphagia, emotional lability |
| Gait disorder | Frontal-pattern gait, small-stepped, wide-based ("marche à petits pas") |
Additional features:
- Hemiparesis
- TIAs
- Lacunar or cortical strokes (often admixed)
- Urinary incontinence (when combined with gait disorder - NPH overlap)
MRI Findings (Key Imaging Features)
From Grainger & Allison's Diagnostic Radiology and Harrison's Principles of Internal Medicine (2025):
FLAIR sequence is the best sequence for detecting small-vessel white matter disease.
| Finding | Description |
|---|---|
| White matter hyperintensities (FLAIR/T2) | Confluent, bilateral, periventricular and deep white matter |
| Distribution | Predominantly frontal and parietal deep white matter |
| Spared areas | U-fibres (subcortical arcuate fibres) and temporal lobes |
| Lacunes | Multiple small hypointense cavities (basal ganglia, centrum semiovale) |
| T1 | Severe lesions become T1 hypointense (tissue destruction) |
| Basal ganglia & pons | Frequently involved |
| DWI | Recent white matter lesions can be bright (acute lacunar infarction) |
Extremely severe diffuse white matter vascular injury is what defines Binswanger's - Harrison's Principles of Internal Medicine, 2025
Fazekas Grading (White Matter Lesion Severity)
| Grade | Description |
|---|---|
| 0 | No lesions |
| 1 | Punctate foci |
| 2 | Beginning confluence |
| 3 | Large confluent areas = consistent with Binswanger's |
The MRI in the patient (Bishan Pandey, 75y) showed Fazekas Grade 3 - the most severe category.
Differential Diagnosis
| Condition | Key Distinguishing Feature |
|---|---|
| CADASIL | Genetic (Notch-3 mutation), younger onset, temporal lobe involvement, family history |
| Multiple Sclerosis | Involves U-fibres and temporal lobes, periventricular lesions are more perpendicular ("Dawson's fingers") |
| Normal Pressure Hydrocephalus | Ventriculomegaly disproportionate to atrophy, classic triad (gait, cognition, incontinence) |
| Alzheimer's Disease | Cortical/hippocampal atrophy predominant, less white matter change |
| CARASIL | Recessive, alopecia, lumbar spondylosis |
Risk Factors
- Hypertension (most important)
- Diabetes mellitus
- Hyperlipidaemia
- Atrial fibrillation
- Smoking
- Advancing age (predominantly 60s-80s)
- Male sex
Management
There is no disease-specific treatment. Management is focused on:
- Aggressive vascular risk factor control
- Antihypertensives (target BP <130/80 mmHg)
- Statins
- Antiplatelet therapy (if stroke/TIA present)
- Glycaemic control
- Cognitive rehabilitation
- Symptomatic treatment of dementia (cholinesterase inhibitors have limited but sometimes used role)
- Fall prevention and physiotherapy for gait disorder
- Carer support and advance care planning
Relation to the Scanned Patient
The MRI findings seen in Bishan Pandey (75y) - confluent bilateral periventricular white matter T2/FLAIR hyperintensities (Fazekas 3), ventriculomegaly, and cortical atrophy - are classic for Binswanger's disease / subcortical ischemic vascular dementia. Clinical correlation with hypertension history, cognitive screening (MoCA/MMSE), and gait assessment is advised.
