                                             9y MC Australian Shepherd with chronic nasal discharge. The left tympanic bulla is fluid
                                             filled and contains multiple discrete mineral opacities. Biopsy acquired during bulla
                                               osteotomy yielded a histologic diagnosis of chronic otitis media with inspissated and
