    Summary

    Magnetic Resonance (MR) imaging effectively diagnoses old brainstem infarcts, particularly in the pons. These lesions often accompany other cerebrovascular conditions.

    Area of Science:

    • Neurology
    • Radiology
    • Neuroimaging

    Context:

    • Brainstem infarcts are a significant cause of neurological deficits.
    • Accurate diagnosis and characterization of brainstem lesions are crucial for patient management.
    • Previous studies have explored various imaging modalities for brainstem pathology.

    Purpose:

    • To evaluate the utility of 1.5T Magnetic Resonance (MR) imaging in diagnosing old brainstem infarcts.
    • To identify the most common locations and characteristics of brainstem infarcts.
    • To determine the frequency of associated supratentorial and subcortical lesions.

    Summary:

    • Thirty-three patients with old brainstem infarcts underwent 1.5T MR imaging.
    • T1-weighted sequences proved most effective for diagnosing brainstem infarcts.
    • Infarcts were most commonly found in the central mid pons; medullary infarcts were right-sided, and midbrain infarcts were large.
    • Brainstem infarcts frequently co-occurred with supratentorial lacunar infarcts and subcortical arteriosclerotic encephalopathy.

    Impact:

    • Highlights the diagnostic value of T1-weighted MR imaging for brainstem infarcts.
    • Provides insights into the topographical distribution and common locations of brainstem lesions.
    • Suggests a potential association between brainstem infarcts and other cerebrovascular pathologies, aiding in comprehensive patient assessment.
