Abstract:
A 38-year-old male suffered sudden onset of rotational vertigo without headache. Consciousness disturbance developed on the 3rd day after the onset. Computed tomography showed cerebellar infarction with obstructive hydrocephalus. External ventricular drainage was performed. Angiography showed bilateral extracranial vertebral artery dissection. Antiplatelet therapy was given. Repeat angiography showed improvement of the dissection. His neurological deficits completely resolved. Vertebral artery dissections may cause both lateral medullary or cerebellar infarction and hydrocephalus due to the cerebellar infarction manifesting as various symptoms so careful evaluation and treatment are required.
