Overview

A complete blood count, routine blood chemical evaluations, the results of a serologic test for syphilis, tests of liver and thyroid function, and a test for antinuclear antibodies, a vitamin B12 level, an electrocardiogram, an x-ray film of the chest, and a toxicity screen were reported to be normal. Another CT scan of the cranium showed no change in the right tentorial meningioma in comparison with the study performed five years earlier; there was marked progression in the low-absorptive, non--contrast-enhancing abnormalities, which involved the right frontal, temporal, parietal, and occipital regions, with less marked findings on the left side; a mass effect created a subfalcial shift toward the left side; the posterior limb of the internal capsule, the external capsule, and the corpus callosum on the right side were involved, as were the left corpus callosum, forceps major, and forceps minor; an area of contrast enhancement, 0.5 cm, was observed in the right temporal subcortical region and was of slightly high-absorptive appearance on the plain scan; cavitary changes were present in the head and adjacent body of the caudate nucleus, abnormalities that were not detected on review of the CT scan performed five years earlier; the cortical sulci were effaced bilaterally.
