After reviewing this educational exhibit, the participant should be able to 1) describe the unique clinical neurological presentation of classic ischemic stroke syndromes and 2) explain their neuroanatomical localization.

Clinical presentation b. Neuroimaging findings 5. Brainstem syndromes a. Clinical presentation b. Neuroimaging findings Summary: The neuroanatomical localization of classic ischemic stroke syndromes is essential for the neurologist and neuroradiologist to help guide the proper ordering and interpretation of neuroimaging studies. In particular, the “gunshot” approach to neuroimaging can be avoided by understanding lesion localization. Multiple syndromes are very classic in clinical presentation and can very well predict the neuroimaging abnormality. The neuroimaging interpretation false negative rate is also likely reduced if the expected abnormal area is closely inspected especially in the hyperacute-subacute setting when CT can be equivocal. Negative diffusion weighted imaging (DWI) ischemic stroke has also been previously described in the brainstem and posterior circulation territory.
