We report a boy who developed a vertebral stroke immediately after an appendectomy. Basilar impression was diagnosed eight years after this event when skull roentgenograms revealed basilar impression with high standing tip of the odontoid. We speculate that muscle relaxation and cervical hyperextension during intubation in the presence of basilar impression resulted in vertebral artery dissection and stroke. We suggest that patients with vertebral stroke and no obvious risk factors should be evaluated for the presence of malformations of the craniovertebral junction to be able to take precautions against excessive neck movement during intubation.
