متن کاملMinimally invasive surgical removal of an intracochlear schwannoma causing an intractable paroxysmal positional vertigo.
Intracochlear schwannomas are rare tumours. Diagnosis is based on high-resolution MRI, which should be used for accurate determination of the location of tumours. We report a case of a cochlear schwannoma that presented with profound hearing loss and intractable paroxysmal positional vertigo, which was diagnosed with gadolinium-enhanced MRI and removed using a transcanal minimally-invasive tran...
متن کاملIntracochlear schwannoma presenting as diffuse cochlear enhancement: diagnostic challenges of a rare cause of deafness

Due to the small size, position, and variable clinical and imaging features, diagnosis presents a significant challenge and is often delayed. We present a case of a patient with an intracochlear schwannoma presenting as a diffuse enhancement of the cochlea, mimicking an infectious or inflammatory process. The absen...
