Patient Data

Age: 35

The mass is durally based and exhibits avid enhancement after contrast administration. No intracanalicular extension.

Case Discussion

This case illustrates typical appearances of a cerebellopontine angle meningioma, a diagnosis which in this instance can be made with a great deal of confidence. The general differential to be considered when evaluating a CPA mass includes:

  • meningioma
  • vestibular shwannoma - in this case there is no intracanalicular extension
  • other clearly non-viable alternative diagnoses
    • epidermoid cyst: no enhancement
    • arachnoid cyst: no enhancement and follow CSF signal in all sequences
    • lipoma: follow fat signal without enhancement
