Two cases of ischemic cerebrovascular disease with only XXXX as neurological symptom and abnormal MR findings.

@entity1 @entity2806 @entity2730 @entity887 @entity1856 @entity732 @entity2414 @entity385
Case 1 involved a 77-year-old @entity1 admitted to our hospital after he lost almost all memory of work on the day before. Diffusion-weighted imaging (DWI) revealed spotty hyperintensities in the bilateral hippocampi, which were considered responsible for the @entity2730 . Transesophageal echocardiography (TEE) showed severe aortic arch @entity1856 , 6.8   mm in diameter with extension to the branch. @entity887 to the bilateral hippocampi was diagnosed. Case 2 involved a 66-year-old @entity1 admitted to our hospital because she had lost all memory of the 5 hours she was out. She had transient anterograde @entity2730 . DWI revealed no @entity2806 , but magnetic resonance angiography (MRA) revealed @entity732 of the right posterior cerebral artery. MRA on hospital day 7 revealed partial recanalization. TEE showed aortic arch @entity1856 of 3.9   mm in diameter with extension to the branch. In both cases, aortogenic @entity887 to the hippocampus might have been causally related to transient @entity2414 . In @entity1 with acute @entity2414 , the possibility of @entity385 should be considered.
