[A case of amnesic syndrome caused by hematoma in the left anterior medial thalamus].
We reported a case of amnestic syndrome caused by a hematoma in the left thalamus. The case was that of a 68-year-old, right-handed man who suddenly showed amnestic syndrome. He had neither motor paresis nor sensory disturbance. Clinical examination showed he had disorientation, anterograde amnesia and mild retrograde amnesia. Immediate recall and remote memory were intact, but recent memory was severely impaired. CT scan revealed a high density area in the anterior medial part of the left thalamus. We concluded that amnesia in this patient was caused by fasciculus mamillothalamicus damage because of a hematoma during thalamic hemorrhage.
