Clinical question: Left unilateral SNHL, spontaneous, presented to years ago. Signs and symptoms: Left unilateral SNHL. Pre- and post enhanced MRI of IAC:Examination demonstrates normal signal intensity, size and morphology of symmetrical bilateral internal auditory canals.Normal signal intensity, morphology of symmetrical bilateral inner ears structures.Normal signal intensity and morphology of bilateral neural vascular bundles across the cerebellopontine angles and within the internal auditory canals. There is no detectable abnormal enhancement in the bilateral cerebellopontine angles, internal auditory canals or in the inner ear structures. Unremarkable signal intensity and morphology of pons and without detectable abnormal enhancement.Normal pneumatization signal pattern of bilateral mastoid air cells and middle ear cavities.Unremarkable images through the skull base without abnormal enhancement.
Negative pre and post enhanced MRI of IACs.
