Lateral abdominal radiograph showing a small calcified prostate, a sublumbar mass (probably adenomegaly) that reinforced the diagnosis of prostate cancer with lymph node metastases in a neutered dog. An irregular osteoproliferation of the ventral edges of L5–L6–L7 also suggested tumor invasion. Periosteal proliferative lesions of the pelvis and femurs were consistent with hypertrophic osteopathy.
