Abstract

A 9-year-old female spayed boxer presented for a dorsal cranial mass. Cytology diagnosed a sarcoma. Contrast-enhanced computed tomography (CT) of the head revealed a symmetrical, soft tissue attenuating mass with subtle mineralization and a contrast-enhancing capsule at the dorsal calvarium. There was adjacent frontal bone lysis and contrast enhancement of the parietal lobe. This supported a sarcoma of bone or cartilage origin. Postmortem examination additionally revealed a pulmonary tumor embolus. A final diagnosis of grade III multilobular osteochondrosarcoma (MLO) was made. This is the first study describing a poorly mineralized, encapsulated MLO in a dog and supports a periosteal origin.

影像学诊断：犬多小叶骨软骨肉瘤的非典型CT表现。

一名九岁雌性阉拳师因背部颅骨肿块就诊。细胞学诊断为肉瘤。头部CT增强扫描显示一对称的软组织衰减肿块伴轻微矿化，颅骨背侧可见增强膜。临近额骨溶解，顶叶造影增强。这支持骨或软骨肉瘤的起源。尸检还发现肺肿瘤栓子。最终诊断为III级多小叶骨软骨肉瘤（MLO）。这是第一个描述狗的矿化不良，包裹MLO并支持骨膜起源的研究。
