Previously described punctate enhancing lesions within the right superior parietal lobule and along the right occipital cortex are no longer distinctly visualized.None of the above mentioned lesions cause any significant edema. No new lesions are identified. No generalized mass effect is detected. The ventricles remain normal in size and morphology.
