Craniomandibular osteopathy in a golden jackal (Canis aureus)

Abstract

Craniomandibular osteopathy is a rare disorder in dogs, characterised by subperiosteal and extraperiosteal new bone proliferations on the skull, on the mandibles in particular and occasionally on long bones. Data about craniomandibular osteopathy in the golden jackal (Canis aureus) are lacking. This paper describes craniomandibular osteopathy in a seven-month-old animal. The mandibular region and the distal section of the hindlimb were examined radiologically and by CT. Both imaging modalities showed ossifying periosteal deposits localised on the left side of the mandible and irregular periosteal ossifying deposits covering the surface of the crural bones. Histopathology revealed new bone formation in the endosteum, periosteum and trabecular bone of the mandible and in the distal section of the hindlimb, but no inflammatory cells were found. Craniomandibular osteopathy in free-living canids has not yet been reported. However, the macroscopic imaging and histopathological features in this pup were consistent with the disease.

Description of a novel distribution and subsequent resolution of severe, bilateral thoracic limb and cervical vertebral abnormalities in a dog with craniomandibular osteopathy

“…CMO is defined as a self-limiting proliferative disorder, 7 although in some cases extensive changes to the bone structure can lead to ankylosis of the TMJ and finally to euthanasia. 8 CMO exists in several small and large breeds, 6 with the highest frequency seen in West Highland white terriers.…”

Osteopatia Craniomandibular Em Pastor Alemão – Relato De Caso

“…A osteopatia craniomandibular, também chamada de osteopatia temporomandibular, periostite mandibular (1) ou mandíbula de leão (2,3) é uma doença óssea proliferativa que afeta cães com idade variável, mas geralmente entre três e oito meses (4) acomete comumente ossos do crânio e não tem natureza neoplásica (3). É considerada uma doença rara (5,6) e existem relatos de evolução e envolvimento em ossos longos (2,7,8) como rádio e ulna (9).…”
