- Also called hypertrophic pulmonary osteopathy
- In all species
- Associated with chronic lesions (intrathoracic neoplasm or space-occupying lesion) usually in the thorax
- Tuberculosis
- Pulmonary neoplasia
- Granulomatous pleuritis
- Granulomatous lymphadenitis of mediastinal nodes
- Grossly:
- Periosteal proliferation of bone on diaphyses of distal limbs
- Progressive and bilateral
- Histologically:
- Hyperaemia of periosteum
- Deposition of new bone
- Width of cortex may double in a few weeks
- Postulated to be due to stimulation of vagus by intrathoracic lesion -> increasing blood floow to extremities -> thickening of periosteum
