Selective anterograde amnesia with thalamus and hippocampal lesions in neuro-Behcetʹs disease

Anterograde amnesia and minimal retrograde amnesia with thalamic and hippocampal lesions in neuro-Behcetʹs disease is rare. A 50-year-old man presented with forgetfulness and severe memory disturbance after suffering multiple oral and genital aphthous ulcers with erythema nodosum. A neurological examination and a neuropsychological assessment revealed prominent anterograde memory impairment without focal neurological deficits. On brain MRI there were high signal intensity lesions involving right anterior thalamus, left posterior basal ganglia, and left hippocampus. This is a quite selective anterogrde memory deficit in a case of neuro-Behcetʹs disease caused by parenchymal lesions in the thalamus and hippocampus.
