Several observers have noted that it is difficult at times to differentiate clinically between occlusion of the posterior inferior cerebellar and the vertebral arteries, and others in reports on the bulbar syndrome have included cases of occlusion of the vertebral artery as well as of the posterior inferior cerebellar artery. Spiller1 (1908) reported two cases with postmortem observations, both, strange to say, showing involvement
