Vestibular Schwannoma presenting as hearing loss.

This 40 year gentlemen presented with gradually deteriorating hearing loss over 1 month in left ear. PURE TONE AUDIOMETRY showed left moderate Sensorineural hearing loss. MRI findings are given below.
Coronal cuts showing left CPA tumour
Axial cuts showing left CPA tumour

Though such findings are rare and this tumour is rare, It's advisable to get  MRI in cases of  nerve deafness especially if  this is unilateral and patient is young. 12 % of cerebellopontine angle tumour may present as sudden deafness which may respond to steroids. All such cases warrants MRI study.
