Male, 66 years old, with metastatic thyroid cancer to the brain, follow-up examination. Evidence is seen compatible with prior lesion resection from the left inferior parietal lobule. Mild T2 hyperintensity and hemosiderin staining at the resection site are unchanged. No pathologic enhancement is seen at this location.A 5 mm enhancing lesion with susceptibility effect in the left superior parietal lobule is unchanged. A 3 mm focus of enhancement in the left postcentral gyrus is unchanged. A vague 3 mm focus of enhancement in the right middle frontal gyrus is unchanged from prior. A nonenhancing focus of susceptibility along the right caudate head is unchanged.No areas of new pathologic enhancement or parenchymal signal abnormality are seen. No evidence of significant edema or mass effect is detected. The ventricles are stable and normal in size.
1.Stable postoperative findings in the left inferior parietal lobule with no evidence of residual or recurrent metastatic tumor.2.Small enhancing foci within the left superior parietal lobule, the left postcentral gyrus and the right middle frontal gyrus are unchanged.
