Intralabyrinthine schwannoma.

H L DeLozier, R R Gacek, S T Dana

    The Annals of Otology, Rhinology, and Laryngology
    |March 1, 1979
    PubMed
    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.
