A 29-year-old male asked:

How rare are retrocochlear lesions/masses? i have had 2 normal iams/head mris in 2013 + 2014 & i understand acoustic neuromas are very rare but what about the other types of retrocochlear lesions/masses involved in progressive unilateral hearing loss?

If you had the hearing loss before the MRI in 2013 and 2014, you should not worry about retrocochlear pathology as the cause of your hearing loss. By UPTODATE: majority of patients with sudden sensorineural hearing loss likely have a viral, autoimmune, or microvascular etiology that cannot be diagnosed by any imaging study.
