    Summary

    Basilar artery ectasia, a condition where the basilar artery widens, was diagnosed using computed tomography (CT). CT imaging accurately showed the artery

    Area of Science:

    • Neurology
    • Vascular Imaging
    • Neuroanatomy

    Background:

    • Basilar artery ectasia is a rare vascular condition.
    • Accurate diagnosis is crucial for understanding neurological symptoms.
    • Computed tomography (CT) is a key imaging modality in neurology.

    Purpose of the Study:

    • To evaluate the utility of computed tomography (CT) in diagnosing basilar artery ectasia.
    • To compare CT findings with angiography in visualizing the basilar artery.
    • To correlate imaging findings with clinical manifestations related to brainstem compression.

    Main Methods:

    • Retrospective analysis of 4 cases with diagnosed basilar artery ectasia.
    • Computed tomography (CT) scans were used for imaging.
    • Comparison of CT imaging with conventional angiography.

    Main Results:

    • Computed tomography (CT) successfully demonstrated basilar artery ectasia in all 4 cases.
    • CT imaging closely matched angiography in depicting the basilar artery's course and diameter.
    • Clinical symptoms correlated with the specific brainstem structures compressed by the ectatic artery.

    Conclusions:

    • Computed tomography (CT) is a reliable method for diagnosing basilar artery ectasia.
    • CT provides accurate anatomical detail comparable to angiography.
    • Understanding the relationship between ectasia and brainstem compression aids in explaining clinical presentations.
