Histopathologic investigation of a case of leucody-strophy is presented in a case who died at the age of 57 years. The illness developed during adult life and had a slowly progressive prolonged clinical course of approximately 7 years. Disturbaces in articulation, muscular rigidity and mental deteriolation were the dominant clinical features. Autopsy revealed an widespread bilateral greyish gelatinous appearance of the cerebral white matter with sparing of the narrow subcortical layer of U fibers. Sections stained for myelin showed diffuse bilateral pallor of the cerebral hemispheres extending througout the centrum ovale and corpus callosum. Holzer stain showed diffuse dense gliosis of the demyelinated areas. A conside-rable loss of axis cylinders was also seen with the formation of many spherical end-bulbes. Perivascular inflammatory cell reaction was minimal or allmost absent. Microglial phagocytes were not abundant and found only scattered throughout the demyelinated area. They contained sudanophil lipid and occasio-nally nonmetachromatic feebly sudanophil materials or light brown pigment staining positively for iron. Histopathological and histochemical examinations sug-gest that this case belongs to the category of suda-nophile leucodystrophy, particularly of late-life ortho chromatic leucodystrophy. Chemical analysis showed decrease in amount of phospholipid, glycolipid, and cholesterol with an increase in amount of esterified cholesterol. No evidence of defective myelin cata-bolism was demonstrated in the demyelinated tissue of this case.
