    This study details a rare case of subarachnoid hemorrhage in a patient with a persistent hypoglossal artery aneurysm. It highlights the extreme rarity of aneurysms occurring directly on the persistent primitive hypoglossal artery.

    Area of Science:

    • Neurology
    • Vascular Neurology
    • Neurosurgery

    Background:

    • Persistent primitive hypoglossal artery (PPHA) is a rare congenital vascular anomaly.
    • Aneurysms associated with PPHA are exceptionally uncommon, with few documented cases.

    Observation:

    • The case involved a patient presenting with subarachnoid hemorrhage.
    • The hemorrhage originated from an aneurysm on the right distal anterior cerebral artery.
    • The patient also had a saccular aneurysm on the left persistent hypoglossal artery.

    Findings:

    • This report documents a saccular aneurysm on a left persistent hypoglossal artery.
    • The patient experienced a subarachnoid hemorrhage secondary to an aneurysm of the right distal anterior cerebral artery.
    • Literature review confirms the extreme rarity of aneurysms arising from the persistent primitive hypoglossal artery itself.

    Implications:

    • This case underscores the importance of considering PPHA in the differential diagnosis of cerebrovascular abnormalities.
    • Further research may elucidate the specific risk factors and pathogenesis of PPHA aneurysms.
    • Understanding these rare vascular variants is crucial for accurate diagnosis and management in neurovascular care.
