Imaging of vestibular schwannoma and other cerebellopontine angle tumors

In this review of cerebellopontine angle tumors, we focus on the most common neoplasm in this location-vestibular schwannoma. We examine both the usual and unusual imaging manifestations of this tumor, which often presents with sensorineural hearing loss, tinnitus, dizziness, and rarely vertigo. We also review key imaging findings that can have significant implications in presurgical planning. Thereafter, we undertake a brief review of the next most common tumors that occur in this location, including meningioma, facial nerve schwannoma, metastasis, and congenital epidermoid cyst. We emphasize distinctive imaging features of these entities, which can help increase our diagnostic accuracy.
