Patients with spinal cerebrospinal fluid (CSF) leaks frequently experience audiovestibular symptoms. While gadolinium-enhanced MRI has been used to detect inner ear abnormalities, no reports have described findings on non-contrast MRI....
✦ Clinical Takeaway ✦
When 3D FLAIR MRI shows inner ear high signal in CSF leak patients, audiologists should be aware this may correlate with audiovestibular symptoms; however, this retrospective study is hypothesis-generating and does not yet justify a change in audiological testing protocols.
✦ Why It Matters ✦
Understanding the MRI signature of inner ear involvement in CSF leaks could help audiologists and neuroradiologists better identify patients whose hearing and balance symptoms have an intracranial structural cause.
✦ Key Points ✦
- 01Inner ear high signal on non-contrast 3D FLAIR MRI was identified in patients with cerebrospinal fluid (CSF) leaks.
