摘要：
An overview is presented of the common and uncommon diseases of the inner ear and of the cochleovestibular nerve within the internal acoustic meatus and cerebellopontine angle cistern causing sensorineural deafness. An imaging-pattern-based approach is used to help detect disease and narrow the differential diagnosis. Main Messages • The m ost c ommon s oft tissue m ass l esions in the cerebellopontine angle are schwannoma and meningioma. • Contrast-enhanced MRI may reveal clinically unsus- pected inflammatory, auto-immune or tumoural disease. • Hearing loss may be caused by infection, inflammation or, rarely, perineural tumour spread along the cochle- ovestibular nerve. • Labyrinthitis may lead to rapidly progressive ossification of the labyrinth. © The Author(s) 2011.
