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)

Literature estimates suggest that 40-70% of traumatic anterior skull base CSF leaks may close spontaneously, but these patients should be monitored closely for recurrence.
