Radiology Cases of Acoustic Neuroma

Radiology Cases of Bilateral Acoustic Neuromas in Neurofibromatosis Type 2

MRI of acoustic schwannomas in a patient with neurofibromatosis Type 2
Axial T1 MRI with contrast of the brain shows bilateral homogeneously enhancing masses in the cebrebellopontine angles. The patient also had an intracranial meningioma.
CT of acoustic neuroma
Axial CT without contrast of the temporal bones shows the left internal auditory canal (right) is smoothly expanded and much larger than the right internal auditory canal (left). This enlargement of the left internal auditory canal corresponded to the location of an enhancing mass within it on an MRI of the brain performed with contrast from an outside institution.
