TGA. MR imaging was performed on a 1.5T scanner 24 hours after the beginning of the clinical symptomatology. On DWI ZOOM-EPI (white arrow in A). a punctate hyperintensity and, on DWI ZOOM-EPI ADC map (white arrow in B), a punctate hypointensity with an ADC of 0.915 × 10⁻³ mm²/second were demonstrated in the left lateral hippocampal body as a specific TGA-associated lesion. ADC in the normal right hippocampus was 1.093 × 10⁻³ mm²/second. Standard DWI (C) did not show the abnormality nor was any signal intensity change visible on transverse FLAIR (D).
