Evaluate any change in size of the cranial bone lesion. Immediately preop. Nonenhanced head CT:A lytic bony lesion of the right parietal lobe along its inferior aspect measuring 12.8 times 6-mm in size. This lesion is similar to prior study in measurement. There is significant thinning of the inner table of the skull however the outer table of the skull is still in tact. There is no epidural soft tissue thickening at this site. Further evaluation with an enhanced MRI or CT is recommended to exclude epidural spread of tumor. The calvarium is otherwise intact. There is no evidence of intracranial hemorrhage, edema, mass effect, midline shift or hydrocephalus.The cortical sulci, ventricular system, CSF cisterns and gray -- white matter differentiations are within normal.
1.Stable small lytic right parietal bone lesion since prior study.2.Negative none diffuse head CT otherwise. A
