Most acoustic neuromas and other tumours seen in NF (Neurofibromatosis) can be detected by an MRI (Magnetic Resonance Imaging), particularly if contrast is used. Unfortunately, cases have been described in the literature of patients who did not have acoustic neuromas but reported dizziness. In these cases, dizziness was caused by tumours in other areas of the central nervous system and not on the VIII nerve (vestibulocochlear nerve).
