CPA masses on MRI

Two patients suffering from hearing loss, each of different etiology with similar but distinguishing MRI findings:

  1. Vestibular Schwannoma: predominant CPA cistern mass with small IAC component forming the so called “ice-cream cone” pattern.
  2. Meningioma: Also CPA cistern mass, however eccentrically straddling IAC with predominant broad base petrous dural origin.

These were captured on a 1.5T Siemens MRI unit also utilized at The Radiology Center of Lyndhurst.
