    AICA aneurysms are rare and often present with subarachnoid hemorrhage, complicating surgical reconstruction due to their morphology and location.

  • 2

    Endovascular parent artery occlusion (PAO) is often necessary for treating ruptured AICA aneurysms, despite risks to the internal auditory artery (IAA).

  • 3

    A 64-year-old male patient experienced facial palsy and hearing loss after ePAO of a ruptured AICA aneurysm, indicating potential complications.

  • 4

    Postoperative recovery included improved facial function and hearing, with significant recovery noted by day 50, despite initial deficits.

  • 5

    This case suggests that neurologic recovery is possible after IAA occlusion, challenging the notion that such deficits are permanent.
