It may occur in young animals by hematogenous spread of infection from omphalophlebitis, but it may also arise from extension of otitis externa or by infection ascending the eustachian tube. Clinical signs are usually referable to an associated otitis externa (odor, discharge, pain) or otitis interna which may cause vestibular signs such as rolling, ataxia and nystagmus.
