Computerised tomography of the brain was performed in 95 patients with multiple sclerosis and in a single patient with Schilder's disease. CT of the orbits was also carried out in 53 of these cases to examine the optic nerves. In 51% of the multiple sclerosis cases low density areas compatible with plaques of demyelination were found in the white matter of the cerebral hemispheres, and less frequently in the brain-stem. A much larger area of reduced intensity was found in the occipital white matter in the patient with Schilder's disease. Varying degrees of central and/or cortical cerebral atrophy were found in 45% of the multiple sclerosis patients, the more severe degrees being found in patients with long-standing disease. Serial observations in 15 patients who were examined on more than one occasion are also presented. Small low density areas were identified in one or both optic nerves in 52% of the multiple sclerosis cases. While these may represent demyelinating lesions their significance is uncertain.
