    Computed tomography (CT) effectively maps internal capsule lesions, aiding diagnosis of pure motor hemiplegia. This study correlated clinical data with CT findings in 25 ischemic capsular lesion cases.

    Area of Science:

    • Neurology
    • Radiology
    • Neuroimaging

    Background:

    • Ischemic strokes affecting the internal capsule often result in pure motor hemiplegia.
    • Accurate localization of these lesions is crucial for diagnosis and treatment planning.

    Purpose of the Study:

    • To localize internal capsule structures on computed tomography (CT) axial sections.
    • To correlate clinical data with CT appearance in ischemic capsular lesions.
    • To evaluate CT's sensitivity and reliability for detecting small, deep cerebral infarcts.

    Main Methods:

    • Analysis of 25 cases with ischemic capsular lesions using routine CT axial sections.
    • Measurement of Hounsfield units (H) in the anterior and posterior limbs of the internal capsule.
    • Classification of lesions based on their topography within the internal capsule.

    Main Results:

    • Computed tomography (CT) successfully localized internal capsule components.
    • Distinct Hounsfield unit values were observed between the anterior (32 H) and posterior (28 H) limbs.
    • Lesions were categorized: anterior limb (3), genu (1), posterior limb (7), and putaminocapsulocaudate (14).
    • CT demonstrated higher sensitivity (8/17 positive) than angiography (2/13 positive) for infarct detection.

    Conclusions:

    • CT is a sensitive and reliable method for investigating small, deep cerebral infarcts.
    • The study successfully correlated clinical presentations, particularly pure motor hemiplegia, with CT findings.
    • CT aids in precise lesion localization within the internal capsule, improving diagnostic accuracy.
