Previous presentations on this channel on the topic of stroke mainly focussed on acute ischemic stroke in the anterior circulation. In this presentation I'll specifically discuss posterior circulation stroke. The role of imaging in posterior circulation stroke cannot be underestimated (well, it can never be underestimated whatever the indication off course :)) because these strokes can present with generalized non-focal symptoms and index of clinical (and radiological) suspicion can be low. Nevertheless, they are associated with considerable morbidity and mortality.
