    Area of Science:

    • Neurology
    • Ophthalmology
    • Cardiology

    Context:

    • Presents a rare case of Kearns' syndrome, a mitochondrial myopathy.
    • Highlights the typical triad: retinitis pigmentosa, ophthalmoplegia, and cardiac conduction defects.

    Purpose:

    • To report an anatomoclinical case study of Kearns' syndrome.
    • To discuss the central nervous system and cardiac pathology in this condition.

    Summary:

    • A 13-year-old presented with neuro-ophthalmic symptoms, progressing to a complete Kearns' syndrome triad after developing atrioventricular block.
    • Autopsy revealed spongiosis in the central nervous system and primary degeneration in cardiac conduction tissue.
    • The case illustrates an unfavorable disease course despite pacemaker intervention.

    Impact:

    • Contributes to understanding the neuropathological findings in Kearns' syndrome.
    • Emphasizes the multisystemic nature and poor prognosis of this mitochondrial disorder.
    • Informs clinical management and research into mitochondrial myopathies.
