Question: A 43 year old female is referred for diplopia on lateral gaze and headache. MRI reveals a gadolinium-enhancing lesion involving the right cavernous sinus. It has a broad base along the dura and lacks a cystic component. The mass is removed via frontotemporal craniotomy and sent for pathological analysis. The pathologist's report describes a benign neoplasm with Psammoma bodies. What is the most likely diagnosis? [Answer will be posted with next week's new question]

Answer to last week's question, "The Leaky Faucet" (April 24, 2017)
