Background: Intracranial dissections have been associated with baroreceptor reflex failure. When this occurs labile hypertension may be observed with its own complications, including but not limited to the clinico-radiographic entity, posterior reversible encephalopathy syndrome (PRES).
Methods: Case report and literature review.
Results: We describe a case of carotid dissection resulting in PRES.
Conclusions: We believe failure of the baroreceptor reflex due to carotid dissection resulted in hypertension and subsequent posterior reversible encephalopathy syndrome.
