Computerized tomographic appearance of hypertensive encephalopathy

D L Rail, G D Perkin

    Archives of Neurology
    |May 1, 1980
    PubMed
    Summary

    Hypertensive encephalopathy causes white matter changes visible on CT scans. These brain abnormalities resolve with treatment, suggesting they are related to fluid buildup from damaged blood vessels.

    Area of Science:

    • Neurology
    • Radiology
    • Pathophysiology

    Background:

    • Hypertensive encephalopathy is a neurological condition characterized by elevated blood pressure.
    • Understanding the neuroimaging findings is crucial for diagnosis and management.

    Observation:

    • Computerized tomographic (CT) scans revealed widespread white matter areas of diminished density.
    • These abnormalities were predominantly located in the superior and posterior regions of the cerebral hemispheres.

    Findings:

    • The observed low-density areas in the white matter resolved completely within three months of initiating treatment.
    • The resolution suggests a reversible nature of the observed brain changes.

    Implications:

    • The findings suggest that these low-density areas represent focal collections of edema fluid.
    • This edema is likely caused by extravasation through ischemic segments of the cerebral vessel walls.
    • This highlights the importance of prompt blood pressure management in preventing potentially reversible brain damage.
