Bilateral vestibulopathy with positive Tullio phenomenon

Area of Science:

• Otolaryngology
• Neuroscience
• Vestibular System Research

Background:

• Bilateral vestibulopathy presents a diagnostic challenge.
• Understanding the relationship between vestibular dysfunction and specific symptoms is crucial.

Observation:

• A 34-year-old patient exhibited bilateral vestibulopathy with unusual noise- and pressure-induced nystagmus.
• Video-based head impulse testing and caloric testing confirmed bilateral vestibular dysfunction.
• Cervical vestibular-evoked myogenic potentials were normal, indicating intact sacculus function.

Findings:

• The positive Tullio phenomenon helped exclude semicircular canal dehiscence syndrome.
• This specific symptom constellation was recently associated with vestibular atelectasis.
• Histopathological findings of vestibular atelectasis provide a potential explanation for the observed symptoms.

Implications:

• This case highlights vestibular atelectasis as a potential cause of complex vestibular symptoms.
• Further research into vestibular atelectasis may improve diagnosis and treatment of related disorders.
• Accurate diagnosis of vestibular disorders is essential for patient management and quality of life.
