Özet
Purpose: Vestibular disorders are characterized by head tilt, ataxia, circling, and
nystagmus resulting from dysfunction of the vestibular system. Vestibular
syndrome is classified as peripheral or central based on neurological examination
findings. Paradoxical Vestibular Syndrome occurs due to involvement of the
cerebellum, particularly the flocculonodular lobe or the caudal cerebellar
peduncle. In such cases, head tilt and rotational movements are observed
contralateral to the lesion, whereas postural reaction deficits are typically
ipsilateral.Material-method: A six-year-old, neutered male Tuxedo cat was presented to
Istanbul University-Cerrahpaşa Veterinary Health Practice and Research Center
with a two-month history of balance loss and circling.Results: Physical examination revealed circling to the left. Computed
Tomography (CT) demonstrated hyperdense content in the ventromedial
compartment of the left tympanic cavity and bulla erosion with bicompartmental
hyperdensity in the right tympanic cavity. Magnetic Resonance Imaging (MRI)
revealed a lesion in the left cerebral hemisphere, suggesting central nervous
system involvement. Based on imaging findings and consultation with the
neurosurgery service, the surgical plan was revised and right ventral bulla
osteotomy (VBO) was performed as the initial procedure. Vestibular signs
persisted postoperatively. The patient received intravenous linezolid for five days,
followed by oral linezolid and corticosteroid therapy.Conclusion: Clinical signs resolved completely within one week. Left VBO was
performed one month later. Tympanic membrane integrity was evaluated using
video otoscopy pre- and postoperatively. No recurrence was observed. This case
demonstrates that Paradoxical Vestibular Syndrome may occur concurrently with
bilateral otitis media and may lead to misleading clinical lateralization. Advanced
imaging modalities are essential for accurate diagnosis and surgical planning.Keywords: Paradoxical vestibular syndrome, vestibular ataxia, cat, ventral bulla
