Hippocampal embolic ischemia. MR imaging was performed on a 1.5T scanner. On DW ZOOM-EPI, 3 acute ischemic infarcts in the right mesencephalon along the pyramidal tract (white arrow), in the left medial occipitotemporal gyrus (white arrow), and in the left hippocampus (white arrowhead) were visible as hyperintense foci in A. On DW ZOOM-EPI ADC, the same infarcts were hypointense in B marked with black arrows and a black arrowhead (with an ADC of 0.817 × 10⁻³ mm²/second compared with the ADC of 1.03 × 10⁻³ mm²/second in the normal right hippocampus). The punctate small hippocampal infarct on the left side was not visible on standard DWI (C) or FLAIR (D).
