In undetermined or lacunar stroke patients, BAH frequency was higher in PCS than in anterior circulation stroke (14\/97, 14.4% vs 10\/216, 4.6%;\n            <jats:italic>P<\/jats:italic>\n            =0.005). National Institutes of Health Stroke Scale score was &lt;4 in 65%. Localization of stroke was predominant in pons or cerebellar territories (71.4%).
