Exam is limited for metastatic disease due to lack of post contrast enhancement. Focal area of well-defined hypodensity in the left posterior parietal region along the high convexity is consistent with vasogenic edema. There is mild effacement of the sulci within this region and may be further evaluated with MRI with contrast as clinically indicated. No acute cortical ischemia is seen.The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses cells are normally pneumatized.The left mastoid air cells appear opacified. The internal auditory canals are patent bilaterally.
