Locclusione dellarteria cerebellare inferiore posteriore o uno dei suoi rami, o dellarteria vertebrale porta alla sindrome midollare laterale nota anche con il. syndrome associated with angiographically proved dissection. Three weeks later, he was discharged without any sequelae. L arteria cerebellare inferiore posteriore (PICA), il più grande ramo dell arteria vertebrale, è uno dei tre principali vasi che riforniscono di sangue arterioso il cervelletto.

A 60-year-old woman is immediately brought to the emergency department due to slurred speech and right arm and leg weakness. AICA generally arises from the caudal third of the basilar artery and supplies the lateral pons, inner ear, middle cerebellar peduncle and the anterior inferior cerebellum 4,5. 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. Anterior inferior cerebellar artery (AICA) territory infarcts are much less common than posterior inferior cerebellar artery (PICA) infarcts. 1 2 Primary etiologies include atherosclerosis, hypertension and other vasculopathic risk factors. While most commonly due to PICA occlusion, other arteries, such as the vertebral artery or branches of PICA, can be involved as well. Two weeks ago, he was treated by a chiropractor for intermittent neck pain. WS is most commonly due to an occlusion of the PICA, resulting in ischemia and infarction of the lateral medulla.
