Chorea‐amyotrophy with chronic hemolytic anemia

Abstract

We studied two siblings with chorea and amyotrophy of adult onset and spherocytic hemolytic anemia. Autopsy revealed an atrophic striatum with iron deposition and spheroid bodies. Degeneration of the substantia nigra and spinal cord anterior horns was seen without iron deposition. The disorder seems to be a variant of the chorea-amyotrophy-acanthocytosis syndrome, and the pathology may account for evidence of parkinsonism and amyotrophy in that syndrome. Acanthocytosis may not be the only hematologic abnormality in this disorder.
