Case ReportsFibromuscular dysplasia with carotid artery dissection presenting as an isolated hemianopsia.
Internal carotid artery (ICA) dissection is a well-known cause of anterior circulation stroke, but its association with posterior circulation stroke has been less commonly reported. The latter situation can arise when there is persistent fetal circulation of the posterior cerebral artery and has, to our knowledge, never been reported in the setting of fibromuscular dysplasia (FMD) involving the ICA. ⋯ Although infrequently reported, carotid disease, including dissection, can be responsible for posterior circulation infarcts. Cervical artery dissection can be related to underlying arteriopathies such as FMD, which must be differentiated from vasculitis and vasospasm.
