AB  - OBJECTIVES: Quantify number of MRI scans obtained in a tertiary neurotology
      practice and identify likelihood of pathologic findings. STUDY DESIGN:
      Retrospective cohort study. SETTING: Tertiary neurotology center. SUBJECTS AND
      METHODS: A retrospective analysis of all adult patients over 20months
      (3/2012-10/2013) where MRI was deemed necessary for evaluation of neurotologic
      complaints. Demographics, clinical history, physical examination, and audiometric
      findings were used to categorize new patients into 7 groups: definite Meniere's
      disease (MD), probable MD, possible MD, vague dizziness, tinnitus only,
      asymmetric hearing loss (HL), and other symptoms to stratify risk for
      retrocochlear tumor and other relevant pathology. RESULTS: 1537 MRI scans were
      performed, 932 of these were for a new diagnosis. Discovering retrocochlear
      tumors was rare (1.4%). Patients with HL had a 0.3% (1/314) chance of
      retrocochlear tumor and 3.2% (10/314) chance of relevant pathology. Patients with
      only unilateral tinnitus had no evidence of retrocochlear tumors, and 3.8% chance
      of finding relevant pathology. Patients with "definite" or "probable" MD had no
      evidence of retrocochlear tumor or other relevant findings. All discovered
      acoustic neuromas were in the "possible MD" category, which had a 9.3% chance of 
      finding all relevant pathology. CONCLUSIONS: In a tertiary neurotology center,
      the likelihood of finding a retrocochlear tumor on MRI is rare. In the current
      study, unilateral tinnitus exclusively, "definite MD," and "probable MD" failed
      to yield a single example of retrocochlear tumor. Patients with "possible MD" had
      the highest probability of finding retrocochlear tumors and other relevant
      pathology.
