Age Related White Matter Reporting

MRI reporting language for white matter changes

Recommended framework. Describe severity, morphology, distribution, interval change, and associated small-vessel-disease markers before providing the most likely etiologic interpretation. Use “white matter hyperintensities of presumed vascular origin” when the imaging pattern supports chronic small-vessel disease.

Mild White Matter Changes

Typical pattern: A few or multiple punctate deep white matter foci and/or thin periventricular caps or lining, without confluence; generally Fazekas grade 1.

Findings / Body

Mild punctate T2/FLAIR hyperintensity is present in the periventricular and deep cerebral white matter, without confluence, most consistent with chronic small-vessel change.

Impression

Mild white matter hyperintensities of presumed vascular origin.

Optional impression variants

Age-appropriateMild chronic cerebral small-vessel changes, within the expected range for age.
Nonspecific patternMild nonspecific cerebral white matter signal changes.
Stable comparisonStable mild chronic cerebral small-vessel changes.
Very limited burdenMinimal nonspecific cerebral white matter signal changes, not greater than expected for age.

Moderate White Matter Changes

Typical pattern: Patchy white matter hyperintensities with early confluence and/or a smooth periventricular halo; generally Fazekas grade 2.

Findings / Body

Moderate patchy and early confluent T2/FLAIR hyperintensity is present in the periventricular and deep cerebral white matter, most consistent with chronic small-vessel change.

Impression

Moderate white matter hyperintensities of presumed vascular origin, consistent with chronic cerebral small-vessel disease.

Optional impression variants

Age-appropriateModerate chronic cerebral small-vessel changes, within the expected range for age.
Age-disproportionateModerate chronic cerebral small-vessel disease, greater than expected for age.
Stable comparisonStable moderate chronic cerebral small-vessel disease.
Risk-factor languageModerate chronic cerebral small-vessel disease. Consider clinical assessment and optimization of modifiable vascular risk factors.

Severe White Matter Changes

Typical pattern: Large confluent deep white matter hyperintensities and/or irregular periventricular abnormality extending into the deep white matter; generally Fazekas grade 3.

Findings / Body

Extensive confluent T2/FLAIR hyperintensity is present throughout the periventricular and deep cerebral white matter, consistent with advanced chronic small-vessel disease.

Impression

Advanced chronic cerebral small-vessel disease with severe confluent white matter hyperintensity burden.

Optional impression variants

Short formSevere chronic cerebral small-vessel ischemic changes.
With lacunesAdvanced cerebral small-vessel disease, including severe confluent white matter hyperintensities and multiple chronic lacunar infarcts.
With microbleedsAdvanced cerebral small-vessel disease with severe confluent white matter hyperintensities and chronic cerebral microhemorrhages.
Stable comparisonStable advanced chronic cerebral small-vessel disease with severe confluent white matter hyperintensity burden.

Preferred Standard Language

Severity	Findings / Body	Impression
Mild	Mild punctate periventricular and deep cerebral white matter T2/FLAIR hyperintensities, without confluence, consistent with chronic small-vessel change.	Mild white matter hyperintensities of presumed vascular origin.
Moderate	Moderate patchy and early confluent periventricular and deep cerebral white matter T2/FLAIR hyperintensities, consistent with chronic small-vessel change.	Moderate chronic cerebral small-vessel disease.
Severe	Extensive confluent periventricular and deep cerebral white matter T2/FLAIR hyperintensities, consistent with advanced chronic small-vessel change.	Advanced chronic cerebral small-vessel disease with severe white matter hyperintensity burden.

Terminology Preference

Preferred: “White matter hyperintensities of presumed vascular origin” or “chronic cerebral small-vessel disease.” Traditional alternative: “Chronic microvascular ischemic changes,” recognizing that this is somewhat more etiologically assertive.

Reporting Notes

Report lacunes, chronic infarcts, microbleeds, superficial siderosis, enlarged perivascular spaces, and atrophy separately rather than subsuming them under the white matter descriptor.
For only a few tiny punctate foci—particularly in a younger or middle-aged adult—consider “minimal nonspecific white matter signal changes” rather than automatically diagnosing vascular disease.
Avoid calling severe confluent disease merely “age-related change”; state the severity and frame it as cerebral small-vessel disease.
Use an age qualifier only when the burden is confidently proportionate or disproportionate to the patient’s age and clinical context.
If morphology or distribution is atypical for small-vessel disease, describe those features and provide a focused differential rather than forcing an age-related label.
