Abstract
A 12-year-old castrated male Pekingese dog was presented with weakness, exercise intolerance, and an episode of coughing started 2 weeks earlier upon presentation. Physical examination revealed a grade II/VI left systolic heart murmur. Echocardiographic examination revealed a pericardial effusion and a mass at the heart base located beside the left atrium. The mass beside the left atrium was also visible on the thoracic radiograph after drainage of the pericardial effusion. An aortic body tumor was definitely diagnosed based on postmortem histopathological examination and immunohistochemical staining for specific markers. The dog lived 234 days after diagnosis with only medical management and without recurrence of the pericardial effusion.
