False-positive magnetic resonance image in the diagnosis of small acoustic neuroma.
A patient presented with sudden hearing loss on her first visit to our department. Gadolinium-DTPA-enhanced magnetic resonance imaging (MRI) of the posterior cranial fossa portrayed an intracanalicular tumour image (2-3 mm), and the pure tone average (PTA) and speech discrimination score (SDS) values were 65 dB and 60 per cent, respectively. Surgical intervention to remove the suspected tumour ...

The patient with an acoustic neuroma may present to the otologist with a variety of clinical features. Classically these include a retrocochlear pattern of sensorineural hearing loss, reduced vestibular response on caloric testing and radiological asymmetry of the internal auditory canals (IAC). The absence of any or all of these features, however, does not exclude the presence of tumour. Five ...

IMAGING FINDINGS Magnetic resonance imaging (MRI) of the brain showed a 1.5to 1.8-cm solid and cystic mass that enhances on T1 with contrast at the right cerebellopontine angle and extends into the internal auditory canal, abutting the cerebellum medially (Figure 1). On the day of treatment a stereolocalization MRI showed a mass in the right cerebellopontine angle extending into the right inter...
