Paradoxical Vestibular Syndrome Secondary to Temporal Bone Osteomyelitis and Chronic Otitis Interna in a Guinea Pig (Cavia Porcellus)

A 3-year-old female intact guinea pig (Cavia porcellus) was presented for torticollis and ocular discharge. On examination, the guinea pig had a left head tilt with corneal ulceration and absent palpebral response of the right eye. Computed tomography showed a soft tissue attenuating mass with multifocal mineralization compressing the caudal cerebellum with moderate lysis of the calvarium. On recheck, the disease had progressed to include ataxia and proprioceptive deficits. Systemic antibiotic therapy was initiated but the guinea pig only exhibited a marginal treatment response.
