The corpus callosum is of normal thickness and the volume of the cerebral hemispheres is preserved. No evidence of parenchymal edema or mass effect is seen. No abnormal extra-axial collections are detected. The ventricles are normal in size and morphology.
Stable size and distribution of lesions compatible with multiple sclerosis.
