A retrospective review of 314 cases of contrast-enhanced magnetic resonance imaging (MRI) of the posterior fossa and internal auditory canals was carried out correlating the presenting symptoms with the scan findings. 7.2% of the cases showed findings on the MRI which could account for the patients' symptoms. Patients with sensorineural hearing loss were more likely to have a positive scan than those presenting with vertigo and/or tinnitus without hearing loss. Acoustic schwannoma was the most common lesion detected. Labyrinthine lesions e.g. cochlear schwannoma, labyrinthitis, congenital labyrinthine abnormality, and central lesions e.g. multiple sclerosis, brainstem glioma were some of the other lesions detected.

We report two cases of sixteen year old female patients with NF1 and hearing loss. One patient had only cafe-au-lait spots, while the other patient had severe manifestations of NF1 in form of kyphoscoliosis, requiring multiple laminectomies, vertiginous attacks and optic radiation glioma seen on MRI. Other investigations included pure tone audiograms, autoimmune inner ear disease (AIED) tests. The patient with slight manifestations of NFI had mild to moderate low frequency bilateral sensorineural hearing loss, which showed 20 dB improvement in hearing threshold with steroid treatment. On the other hand, the patient with severe manifestations of NFI disease had profound sensorineural hearing loss with vertiginous episodes. Hearing loss which is usually seen in patients with acoustic neuroma, neurofibromatosis type II, is also an important symptom in patients with neurofibromatosis type I.
