Positive findings on MRI in patients with asymmetrical SNHL

This is a retrospective study of 100 consecutive patients who attended our ENT outpatient clinic in 6 month-period from April to September 2006. All of them presented with Asymmetrical SNHL. They were all investigated with MRI scan of the IAM and CPA. We did not employ any guidelines or protocols as to when to request MRI in patients with Asymmetrical SNHL. The mean age for the studied group was 52.97. Gender distribution in the studied group was 53% for males and 47% for females. The pickup rate was 1% for CPA lesion which was vestibular schwannoma. However, incidentally, there were 15% of cases with vascular loop at the CPA.
