Lethargic, slow to rise
section content
- soft tissue mass in right cranial lung lobe
- periosteal reaction along the diaphyseal cortices of both humeri
- rounded soft tissue mass in ventral aspect of cranial abdomen on left lateral view
- Probable primary pulmonary neoplasm of the right cranial lung lobe; metastatic neoplasm, abscess, granuloma, possible but less likely
- Hypertrophic osteopathy, secondary to pulmonary pathology
- Possible cranial abdominal mass (unlikely to be gastric pylorus, since this is a left lateral recumbent view)
- Radiographic examination of extremities to confirm HO
- FNA or biopsy of lung mass
- Abdominal radiographs and/or ultrasound to evaluate for suspected mass
- CT of thorax to evaluate for evidence of metastases, particularly if surgical removal of large mass is to be considered
