A 65-year-old woman presented with complaints of bilateral hearing loss. Her medical history was significant for repeated otitis media, with 1 episode of tympanic membrane perforation 1 year earlier that had healed spontaneously. Clinical examination revealed no abnormalities except for hearing loss. Her audiogram demonstrated asymmetrical high-frequency sensorineural hearing loss, which was worse in the right ear, prompting further workup with magnetic resonance imaging to rule out acoustic neuroma.

A high-resolution magnetic resonance image obtained for evaluation of retrocochlear pathology did not show any abnormality in the internal auditory canals or the inner ear structures of either ear. However, another abnormality was noted. A high-resolution T2-weighted image (Figure 1), a postgadolinium T1-weighted image (Figure 2), and a high-resolution bone window computed tomographic scan of the temporal bone (Figure 3) were also obtained.
