Neuropathologic correlation of computerized tomography in Huntington's disease.

CT has proved a useful adjunct to the clinical examination in the differential diagnosis of chorea in adults. The CT abnormalities in cases of Huntington's disease are compared with those of a pathologically verified case of Huntington's disease cut in the CT scan plane of tomography. Relative measurements of caudate atrophy on CT agree well with atrophic processes noted neuropathologically.
