RT Journal Article SR Electronic T1 Variant carotid origin of left anterior inferior cerebellar artery mimicking infarct on angiography JF Journal of NeuroInterventional Surgery JO J NeuroIntervent Surg FD BMJ Publishing Group Ltd. SP 279 OP 281 DO 10.1136/jnis.2010.003822 VO 3 IS 3 A1 Bykowski, Julie A1 Jahan, Reza A1 Pakbaz, R Sean YR 2011 UL http://jnis.bmj.com/content/3/3/279.abstract AB A case is presented of a rare anterior inferior cerebellar artery variant, originating from the internal carotid artery. This mimicked a cerebellar infarct on vertebral angiography of a patient who presented with dysmetria and gait imbalance. It is important for the neuroradiologist and neurointerventionist to be aware of common and unusual cerebellar arterial anatomic variants to avoid incorrect diagnoses, as well as understand possible implications for surgery and interventional therapies.
