We describe a patient who had isolated retrograde amnesia of 1-year duration without anterograde amnesia after recovery from encephalitis. Single photon emission computed tomography using 123I-IMP revealed the left temporal lobe abnormality. We postulate that the learning ability for new information and recalling ability for old information involve different neural structure and there is a possible relationship between isolated retrograde amnesia are left temporal dysfunction.
