    Summary

    The trigeminal artery, a common cerebrovascular remnant, can rarely develop aneurysms. This study details a new case of a primitive trigeminal artery aneurysm and its management.

    Area of Science:

    • Neurology
    • Vascular Biology
    • Developmental Biology

    Background:

    • The trigeminal artery is the most frequent persistent carotid-basilar anastomosis in adults.
    • Its presence suggests a potential defect in embryonic cerebrovascular development.
    • Associated congenital abnormalities, like cerebral aneurysms, can occur.

    Observation:

    • A rare case of an aneurysm originating directly from the primitive trigeminal artery is presented.
    • This specific type of aneurysm is exceptionally uncommon.

    Findings:

    • The study documents a novel instance of a primitive trigeminal artery aneurysm.
    • Analysis of the case contributes to understanding the pathology of these rare vascular lesions.

    Implications:

    • This case highlights the importance of recognizing primitive trigeminal artery aneurysms.
    • Understanding the significance and treatment of these aneurysms is crucial for patient management.
    • Further research may elucidate the developmental mechanisms leading to these rare aneurysms.
