%X When an ischemic stroke occurs due to bone or cartilage dynamically affecting vessels supplying the brain, it is called bony stroke. We herein report a patient with recurrent cryptogenic stroke that was thought to be a bony stroke. Dynamic three-dimensional computed tomography angiography revealed mechanical compression of the vertebral artery by the hyoid bone and thyroid cartilage. The patient had a recurrent stroke during antiplatelet therapy. Surgical removal of bone tissue prevents stroke recurrence.
