Diffusion lesions detectable in patients with a transient global amnesia (TGA). (A) An anatomic template showing the various subfields of the hippocampal cornu ammonis according to Lorente de No. (B) The distribution of the DWI/T2 lesions within the cornu ammonis show that the lesions are confined to the CA1 subfield. (C) A model of the hippocampus in axial orientation showing the anterior–posterior distribution of the magnetic resonance imaging (MRI) lesions in TGA. (D) A representative 3 T MRI in a patient with TGA, showing the typical lesion in the diffusion-weighted imaging and apparent diffusion coefficient (ADC) map and the corresponding lesions in the T2-weighted images. Post hoc comparisons (t-test) of ADC between time periods indicate a significant increase in ADC from day 2 to days 4 to 5. *P<0.05.
