Female, 79 years old, with history of right sphenoid wing meningioma. Follow-up exam. Again seen is a homogeneously enhancing extra-axial mass within the right middle cranial fossa. As before, the lesion demonstrates a broad base of contact along the greater sphenoid wing, lateral margin of the right cavernous sinus and right anterior clinoid process. Since the prior examination, there has been no significant interval change in the size or morphology of this lesion.The adjacent parenchyma of the right temporal lobe and inferior frontal lobe is displaced by this lesion, but no parenchymal edema is detected. The lesion abuts the terminal right ICA but with preservation of the flow void. The right optic nerve passes along the medial margin of the lesion but does not appear to be severely impinged.Numerous patchy periventricular and subcortical T2 hyperintensities are again seen, not significantly changed from the prior examination. No evidence of restricted diffusion is detected.No parenchymal edema or new mass effect is seen. No evidence of acute intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricles are within normal limits for size.
1.Stable presumed meningioma within the right middle cranial fossa with a broad base of contact along the sphenoid wing, lateral cavernous sinus wall and anterior clinoid process.2.Stable sequela of moderately advanced chronic microvascular ischemic disease.
