Bilateral Occipital Lobe Infarction in Acute Migraine: Clinical, Neurophysiological, and Neuroradiological Study.

Authors


Abstract

SYNOPSIS

A woman having common migraine attacks coincident with an asymmetrical bilateral occipital lobs infarction that spared the brainstem and cerebellum underwent these studies: serial electroencephalography, brainstem auditory, visual end somatosensory evoked potentials, magnetic resonance imaging of the brain and cerebral arteriography. The patient's vision improved greatly during a one-year followup. The absence of risk factors for stroke suggested that migraine caused the infarction in the posterior circulation network. The pathophysiological mechanisms of stroke in migraine remains speculative.
