Diffusion-Weighted MRI in Transient Global Amnesia Precipitated by Cerebral Angiography Stroke 28:2311-2314, Woolfenden,A.R.,et al, 1997 See this aricle in Pubmed Article Abstract A 44 year old man underwent posterior circulation cerebral angiography for the investigation of episodic vertigo.Shortly after completion of the procedure,he was noted to have symptoms of transient global amnesia. Diffusion-weighted MRI at 6 and 44 hours after the procedure demonstrated increased signal in the right hippocampus and other areas within the posterior circulation bilaterally consistent with ischemia from emboli. Abnormalities on conventional MRI images performed at the same time points were noted only in retrospect.A followup MRI at 2 months was normal. Ischemia from cerebral emboli may cause transient global amnesia precipitated by cerebral angiography.Diffusion-weighted MRI may be useful in defining the pathophysiology.
