An 11-year-old, male, Pekinese was examined because of a sporadic, nonresponsive, nonproductive cough. Radiographically there was cardiomegaly and a soft tissue mass in the cranial mediastinum. Echocardiographically, chronic degenerative valvular disease was diagnosed. Furthermore, a large anechoic structure located cranial to the right atrium was detected. Computed tomography was performed to define the mediastinal mass and a right auricle aneurysm was diagnosed. The dog died suddenly 1 day after the diagnostic imaging procedures. At necropsy, a right auricular aneurysm without discontinuity of the pericardial sac was confirmed. Intrapericardial right auricular aneurysm should be included in the differential diagnoses of cranial mediastinal masses.
一只11岁的雄性北京犬因偶发性、无反应性、干咳前来检查。影像学检查显示心脏增大，前纵隔有一软组织肿块。超声心动图诊断为慢性退行性瓣膜病。此外，在右心房前方检测到一个大的无回声结构。进行计算机断层扫描以确定纵隔肿块，诊断为右心耳动脉瘤。这只狗在诊断性成像检查后1天突然死亡。尸检证实为心包囊完整的右心耳动脉瘤。心包内右心耳动脉瘤应列入前纵隔肿块的鉴别诊断中。
