  • A 51-year-old man developed anterograde amnesia following the ingestion of glufosinate ammonium. Brain MRI revealed hyperintense lesions involving the bilateral hippocampus and parahippocampal gyrus, and the right occipital lobe. The mechanism underlying acute glufosinate ammonium intoxication and the differential diagnosis of hippocampal lesions are discussed.

  • Transient global amnesia(TGA) is a clinical syndrome characterized by sudden, temporary dysfunction of anterograde and recent retrograde memory without other neurologic deficits. Different hypotheses have been considered for its etiology, but it still remains obscure. Recently the diffusion-weighted magnetic resonance imaging(DWI), has been considered as the sensitive tool to detect small punctate hyperintense lesions in the hippocampus in transient global amnesia(TGA). We report two TGA cases, all of them answers to TGA clinical criteria, and one of them showed two dot like high signal intense foci in Rt. hippocampus on DWI.
