Endolymphatic hydrops in patients with migraine: a correlative study.
Front Neurol | 2026
Observational studySummary
This study looked at endolymphatic hydrops (EH) in migraine patients. EH is a hallmark of Menière's disease. Researchers examined MRI scans to find correlations with migraine biomarkers. They reviewed 144 inner ear MRI scans from 108 patients with confirmed EH. Two radiologists graded EH and assessed migraine markers such as white matter lesions. They also measured cranial nerve volumes. The average age of participants was 54 years, with 57% being female. Most patients had grade 2 vestibular EH. About 34-43% had grade 2 cochlear EH. No significant associations were found between EH and migraine biomarkers or cranial nerve volumes. However, left vestibular EH grade 1 was linked to sudden hearing loss. Additionally, left cochlear EH grade 1 was connected to aural fullness. Overall, EH severity did not correlate with known migraine MRI biomarkers in this study cohort. Clinical relevance: This research indicates that endolymphatic hydrops and migraine biomarkers may be distinct, impacting diagnostic and treatment approaches.
Key Learning Points
- Endolymphatic hydrops is commonly observed in migraine patients but does not correlate with known migraine biomarkers in this study.
- Most patients with endolymphatic hydrops had grade 2 vestibular and cochlear EH, indicating varying severity levels.
- Left vestibular hydrops grade 1 is associated with sudden hearing loss, highlighting a potential clinical concern.
- Left cochlear hydrops grade 1 is linked to aural fullness, which may affect patient quality of life.
- The findings suggest that endolymphatic hydrops and migraine may require different diagnostic and treatment strategies.
