We describe the case of a patient who had infarction of the posterior inferior cerebellar artery (PICA) after a chiropractic cervical manipulation. A 39-year-old man visited the emergency room with signs of cerebellar dysfunction, presenting with a 6-hour history of vertigo and imbalance. Two weeks ago, he was treated by a chiropractor for intermittent neck pain. At the time of admission, brain computed tomography, magnetic resonance imaging, and angiography revealed an acute infarction in the left PICA territory and occlusion of the extracranial vertebral artery (VA; V1/2 junction) as a result of the dissection of the VA. Angiography revealed complete occlusion of the left PICA and arterial dissection was shown in the extracranial portion of the VA. He was treated with antiplatelet therapy. Three weeks later, he was discharged without any sequelae. The possibility of VA dissection should be considered at least once in patients presenting with cerebellar dysfunctions with a recent history of chiropractic cervical manipulation.
