    This study presents vascular abnormalities linked to the persistent trigeminal artery. A rare persistent otic artery variant is highlighted as a unique case.

    Area of Science:

    • Neurology
    • Vascular Anatomy

    Background:

    • The persistent trigeminal artery (PTA) is a rare embryological remnant of the cranial vasculature.
    • Understanding variations in the PTA is crucial for diagnosing and managing cerebrovascular diseases.

    Observation:

    • This report details multiple cases exhibiting vascular abnormalities in conjunction with the persistent trigeminal artery.
    • A specific variant, the persistent otic artery, is identified and discussed.

    Findings:

    • The persistent otic artery variant represents a previously undocumented association with vascular abnormalities.
    • These findings expand the spectrum of known PTA-related vascular anomalies.

    Implications:

    • The identification of the persistent otic artery variant may necessitate revised diagnostic and treatment strategies for associated vascular conditions.

  • Further research into the embryological origins and clinical significance of PTA variants is warranted.
