Summary
Intralabyrinthine schwannomas can mimic Ménière's disease. Early recognition in patients with atypical symptoms and negative imaging is crucial for timely diagnosis and treatment.
Area of Science:
- Neurology
- Otolaryngology
- Neurosurgery
Background:
- Intralabyrinthine schwannomas are rare tumors arising within the inner ear.
- They can present with symptoms overlapping those of Ménière's disease, complicating diagnosis.
Observation:
- Two cases of unsuspected intralabyrinthine schwannoma are presented.
- Patients typically present with hearing loss, dizziness, and tinnitus.
- Profound sensorineural hearing loss with poor speech discrimination is common.
Findings:
- Radiographic evaluation was frequently negative, leading to misdiagnosis.
- Five out of six patients were initially diagnosed with Ménière's disease.
- Transcanal labyrinthectomy was the surgical approach for tumor removal.
Implications:
- Atypical Ménière's disease symptoms with negative imaging warrant consideration of intralabyrinthine schwannoma.
- Increased awareness can improve diagnostic accuracy and patient outcomes.
- This highlights the importance of considering rare pathologies in challenging cases.
