title: Subarachnoid hemorrhage presenting an "abnormal movement"--case report.
abstract: A 61-year-old male presented with subarachnoid hemorrhage manifesting an abnormal movement as the initial symptom. The movement was rhythmic with phases: tongue protrusion with eyes wide open, and tongue retraction with eyes closed, lasting for about 10 minutes. Neuroradiological methods identified a small aneurysm as the origin of the hemorrhage. The movement never after recurred clipping the aneurysm and clot drainage. Transient increase in the intracranial pressure was thought to be the cause.
