There is associated hyperostosis of the planum sphenoidale secondary to prior meningioma. Focal soft-tissue prominence within the surgical bed, may represent tumor recurrence. However this is a nonspecific appearance. For further clinical evaluation MRI may be considered.There is ex vacuo dilation of the frontal horns of the lateral ventricles secondary to postsurgical change. The remaining ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are otherwise radiographically normal.
