Cardiac Mass In An 11-year-old MN Doberman Pinscher: Our Case Of the Month Feb. 2020

Patient presented for newly diagnosed grade 2/6 heart murmur, sudden weight loss, and newly diagnosed hypothyroidism. Previous history of random vocalization- unsure if from anxiety or discomfort.

Patient presented for newly diagnosed grade 2/6 heart murmur, sudden weight loss, and newly diagnosed hypothyroidism. Previous history of random vocalization- unsure if from anxiety or discomfort.

DX

Right ventricular papillary mass obstructing the pulmonary outflow. Flattened ventricular septum. Secondary pulmonary hypertension. Concurrent aortic insufficiency. Splenic mass.

Outcome

Given the splenic mass combination with the right ventricular mass hemangiosarcoma or similar sarcoma is
likely. Chemotherapeutic trial can be considered in this patient to reduce mass volume with Doxorubicin or similar. This may also reduce the splenic mass. Oncological intervention is recommended. The patient was humanely euthanized due to quality of life issues.

Image Interpretation

Flattened ventricular septum was noted as well. Aortic insufficiency was present on color flow Doppler. The right atrium was mildly enlarged with significant tricuspid insufficiency with velocities consistent with severe pulmonary hypertension. Right ventricular septum revealed a mixed, hypoechoic mass. Given the splenic pathology metastatic hemangiosarcoma is likely. The mass entered into the right ventricle and measured approximately 3.0 cm. No pericardial effusion was noted. However, the right ventricular mass entered into the pulmonary outflow as well. This created an obstructive flow pattern. There was mild volume overload noted in the right ventricle as well. Spleen – The spleen revealed a moderately complex, mixed hypoechoic expansive mass that measured approximately 6.0 cm.
