    Computed tomography (CT) revealed progressive abnormalities in most moyamoya disease patients, including evolving lesions and cerebral atrophy. Abnormal vascular networks were visualized, indicating disease progression over time.

    Area of Science:

    • Neurology
    • Radiology
    • Medical Imaging

    Background:

    • Moyamoya disease is a rare cerebrovascular disorder characterized by progressive stenosis of the internal carotid arteries and their branches.
    • Understanding the evolution of imaging findings in moyamoya disease is crucial for diagnosis and management.

    Purpose of the Study:

    • To analyze the changes in computed tomography (CT) findings in patients with moyamoya disease over time.
    • To correlate CT findings with clinical and angiographic progression.

    Main Methods:

    • Retrospective review of CT scans from 18 patients diagnosed with moyamoya disease.
    • Analysis of precontrast and postcontrast CT scans, including follow-up examinations.
    • Assessment of lesion evolution, ventricular size, cerebral atrophy, and visualization of abnormal vascular networks.

    Main Results:

    • Initial CT scans showed abnormalities in 17 out of 18 patients, including low density lesions, ventricular dilatation, and cerebral atrophy.
    • Follow-up CT scans in 10 out of 13 patients revealed progression of low density lesions, ventricular dilatation, and cerebral atrophy.
    • Abnormal vascular networks in the basal ganglia were visualized in five patients.
    • CT findings demonstrated evolution consistent with multiple cerebral infarctions and vascular abnormalities.

    Conclusions:

    • Computed tomography is valuable in detecting and monitoring the progression of moyamoya disease.
    • CT findings evolve over time, reflecting the dynamic nature of the disease process.
    • The study highlights the utility of CT in visualizing characteristic pathological changes in moyamoya disease.
