An example of spontaneous migration of a metallic foreign body within the subarachnoid space is illustrated. An intracranial bullet is shown to move within the cisterns of the posterior fossa and then down the subarachnoid space of the spinal canal. The patient's symptoms correlate well with the movement of the foreign body.
