A 6-year-old, 35-kg, female spayed German wirehaired pointer was referred for evaluation of collapse/seizure-like activity and a suspected mediastinal mass. Echocardiographic examination revealed an obstructive, intraluminal aortic mass with aortic dissection. Gross and histopathological findings confirmed the aortic dissection with right pulmonary artery compression and an aortopulmonary fistula. The mass was histologically consistent with an intraluminal chondrosarcoma. To the authors knowledge this case represents only the second case of aortic chondrosarcoma in a dog, and interestingly the first case in either a dog or human to have aortic dissection associated with aortic obstruction by an intraluminal aortic tumor.
一只6岁、体重35千克的雌性绝育德国刚毛指示犬因出现虚脱/癫痫样发作以及疑似纵隔肿物而被转诊进行评估。超声心动图检查发现主动脉腔内有一阻塞性肿物并伴有主动脉夹层。大体和组织病理学检查结果证实存在主动脉夹层，伴有右肺动脉受压以及主肺动脉瘘。该肿物在组织学上与腔内软骨肉瘤相符。据作者所知，此病例是犬类主动脉软骨肉瘤的第二例，有趣的是，无论是在犬类还是人类中，这都是首例因腔内主动脉肿瘤导致主动脉阻塞并伴有主动脉夹层的病例。
