Multifocal CT enhancement in MS.

G C Ebers, F V Vinuela, T Feasby

    Neurology

    Summary
    This summary is machine-generated.

    Enhancing lesions on CT scans in multiple sclerosis (MS) indicate active disease, particularly during acute relapses. These findings suggest MS relapses are often multifocal and potentially driven by blood-borne factors.

    Area of Science:

    • Neurology
    • Radiology
    • Immunology

    Background:

    • Multiple Sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system.
    • Contrast-enhanced Computed Tomography (CT) is utilized to assess disease activity in MS patients.

    Observation:

    • A review of 146 CT scans from 125 MS patients was conducted.
    • Enhancing lesions were identified in 53.4% of scans during acute relapses, 40.8% during the "active" disease stage, and 12.5% during clinically inactive periods.

    Findings:

    • Enhancing lesions on CT scans in MS patients correlate with active biologic disease.
    • Autopsy confirmed enhancing lesions represent demyelinating plaques.
    • Over half of hospitalized MS patients with acute attacks exhibited multifocal relapses.

    Implications:

    • Enhancing lesions are most prevalent during acute, clinically apparent MS relapses.
    • The multifocal nature of acute MS relapses suggests a potential role for blood-borne factors in disease pathogenesis.
    • These findings aid in understanding MS disease activity and progression.
