• Rare, represent 0.7 to 4% of all posterior fossa meningiomas (Thomas et al. 2015)
• Present in 4th or 5th decade of life; more common in females (Thomas et al. 2015)
• Common presenting symptoms include hearing loss, tinnitus, and middle ear mass (Thomas et al. 2015)
• Look for permeative-sclerotic bony erosions on CT and tumor spread along dural surfaces on post-contrast T1 MR
• Typically large at presentation with poorly-defined margins and centrifugal spread, especially along dura
• Treatment involves observation with serial imaging, surgery, or radiation (Tolisano et al. 2018)
• On CT: hyperdense mass with permeative-sclerotic bony changes without contrast; high density with contrast
• CT spread patterns:
  • Superolateral to middle-ear mastoid space
  • Lateral to CN VII mastoid segment
  • Anterior to horizontal petrous ICA canal
  • Anteromedial to petrous apex
• On MR:
  • Hypo- to isointense on T1 with ABSENT flow voids and rarely bright calcifications
  • Hypointense on T2
  • FLAIR hyperintense
  • T1 post-contrast is hyperintense with good definition of spread
