What is the most likely diagnosis in these scans of an 18 years old girl?
- Epidermoid cyst
- Vestibular schwannoma
- Meningioma
- Arachnoid cyst
- 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.
