A one-year-old male mongrel dog was referred to the Veterinary Clinic with a several-week history of lameness and pain of the right front leg. Radiological examination of the right humerus revealed a cystic lesion at the distal end of the bone; the lesion was nodular in a gross appearance. Histologically, the nodular lesion consisted of large areas of haemorrhage and thick fibrous trabeculae mixed with a variably dilated cavernous structure of blood vessels attributed to haemangiosarcoma. Based on these findings, aneurysmal bone cyst secondary to the tumour was diagnosed.
一只一岁的雄性杂种犬因右前肢跛行和疼痛数周被转诊至兽医诊所。对右肱骨进行放射学检查发现骨远端有一个囊性病变；该病变外观呈结节状。组织学上，结节性病变由大面积出血和粗大的纤维小梁组成，混有因血管肉瘤导致的不同程度扩张的海绵状血管结构。基于这些发现，诊断为继发于肿瘤的动脉瘤样骨囊肿。
