[Case report: Hypertrophic osteopathy in roe deer (Capreolus capreolus)].

This report describes a case of hypertrophic osteopathy in an approximately three years old male roe deer (Capreolus capreolus). The hunter reported that the animal was apparently healthy and showed no signs of movement imparities. At dissection, a combination of a lung abscess with bony swellings at the distal parts of the limbs was observed. Further investigation revealed that the bony swellings were caused by a severe periosteal hyperosteosis at the diaphyses of the digital phalanges, metacarpal and metatarsal bones. The periosteal new bone was characterized by the formation of coralliform osteophytes, typically seen in cases of hypertrophic osteopathy. As usual in animals with hypertrophic osteopathy, the pathological changes in this roe deer developed secondary to a intrathoracic lesion (lung abscess).
