CAE cause characteristic gyriform infarction patterns on MRI that are distinct from typical cardioembolic stroke. In addition, cortical borderzone predilection and multifocal infarctions were substantially more frequent in CAE. This constellation of findings, in the appropriate clinical context, should strongly suggest CAE as the mechanism of neurologic injury, and may facilitate timely identification of this uncommon but critical diagnosis.
Ullman et al. (Mon,) studied this question.
