What is the most likely diagnosis in these scans of an 18 years old girl?

  1. Epidermoid cyst
  2. Vestibular schwannoma
  3. Meningioma
  4. Arachnoid cyst
  5. Metastasis

Answer

Congratulations to those who guessed meningioma. It is an extra-axial, contrast-enhancing lesion, often with homogenous enhancement and a dural tail. A vestibular schwannoma would cause widening of the auditory canal.
