A free-ranging powerful owl (Ninox strenua) presented in a dull state with extensive bruising of the skin overlying the skull, due to suspected trauma. Supportive care was provided, which resulted in the return to a normal state, although intermittent subtle neurologic abnormalities remained. One month from original presentation, intermittent episodes of head turning and a possible seizure were noted, but behavior and appetite were otherwise normal. The owl was referred to Taronga Wildlife Hospital for evaluation. On presentation, the owl exhibited severe neurologic abnormalities, prompting euthanasia. At necropsy the dorsum of the skull exhibited marked osseous proliferation, extending ventrally and compressing the cerebrum. The skull was radiographed and submitted for histopathology. A diagnosis of osteoblastic osteosarcoma was made. This is the first report of a calvarial osteosarcoma in a powerful owl.
一只自由放养的猛鸮（褐鹰鸮，Ninox strenua）因疑似外伤，呈现精神萎靡状态，其颅骨上方皮肤有大面积瘀伤。给予了支持性护理，猛鸮恢复到正常状态，不过仍间歇性存在轻微神经功能异常。自首次出现症状起一个月后，发现猛鸮有间歇性转头现象，可能发生了癫痫，但行为和食欲正常。这只猛鸮被转诊至塔龙加野生动物医院进行评估。就诊时，猛鸮表现出严重的神经功能异常，遂实施安乐死。尸检时发现颅骨背面有明显的骨质增生，向腹侧延伸并压迫大脑。对颅骨进行了X光检查，并送去做组织病理学检查。诊断为成骨性骨肉瘤。这是关于猛鸮颅骨骨肉瘤的首例报告。
