    Area of Science:

    • Rheumatology
    • Vascular Medicine
    • Internal Medicine

    Background:

    • Giant-cell arteritis (GCA), also known as temporal arteritis, is a systemic inflammatory disease affecting large and medium-sized arteries.
    • It primarily impacts individuals over 50 years of age, posing a significant risk for serious complications.

    Observation:

    • Common initial symptoms include headache, scalp tenderness, jaw claudication, fever, and fatigue.
    • A critical and often irreversible complication is sudden vision loss.
    • GCA can manifest with diverse and less common symptoms, including limb claudication, stroke, and myocardial infarction.

    Findings:

    • The precise etiology of giant-cell arteritis remains unknown.
    • While typical symptoms are recognized by emergency physicians, atypical presentations can delay diagnosis.

  • Prompt initiation of corticosteroid therapy is essential for managing GCA.

    • Implications:

    • Early diagnosis and treatment of GCA are vital to prevent irreversible morbidity, particularly blindness.
    • Awareness of both common and unusual GCA manifestations is crucial for effective emergency medical management.
    • Timely intervention with steroids can significantly reduce the long-term complications associated with this vasculitic condition.
