A 16-year-old showjumping gelding was examined because of a non-painful, slowly progressive caudal thigh swelling, which was associated with 2/10th lameness at the trot. Radiography, real time beta-mode ultrasonography and gamma-scintigraphy of the caudal thigh for the presence of chip fractures, sequestrum formation and, or, abscessation were inconclusive. Radiographic examination of the chest revealed multifocal, nodular cannon ball-like opacities throughout the entire lung fields from which a diagnosis of a primary soft tissue tumour with metastasis to the thorax was made. An anaplastic sarcoma was diagnosed port mortem in the candal thigh. At no time did the horse show signs of respiratory embarrassment.
一匹16岁的场地障碍赛 gelding（此处geldin可能有误，推测为雄马“gelding”）因无痛性、缓慢进展的大腿后侧肿胀接受检查，该肿胀与小跑时2/10的跛行有关。对大腿后侧进行X线摄影、实时B型超声检查和γ闪烁扫描，以检查是否存在碎骨片骨折、死骨形成和/或脓肿，但结果不明确。胸部X线检查显示整个肺野有多灶性、结节状炮弹样阴影，据此诊断为原发性软组织肿瘤伴胸部转移。尸检时在大腿后侧诊断出未分化肉瘤。这匹马从未出现呼吸窘迫的迹象。
