Plain-English summary
A 6-year-old Pomeranian was diagnosed with a serious heart tumor called hemangiosarcoma, which had spread to the lungs. The dog showed signs of heart issues, and an ultrasound revealed a tumor in the right atrium along with fluid around the heart. Unfortunately, chest X-rays didn't show the lung metastases, which were only discovered during an autopsy. This case highlights the importance of thorough testing, including advanced imaging like CT scans, to fully understand the extent of such tumors.

Abstract
Cardiac tumors are rare in animals. They can be both primary and metastatic. The most common canine cardiac tumor is hemangiosarcoma. This is a malignant tumor that in most cases is localized in the right heart and metastasizes mainly to the lungs. The article presents a clinical case of right atrium hemangiosarcoma with metastatic lung lesions in a six-year-old Pomeranian. А tumor in the right atrium and а moderate amount of pericardial effusion was detected on echocardiography. However, chest X-ray data did not allow us to determine the presence of lung metastases, which were detected during autopsy. This clinical case demonstrates the characteristic localization of the tumor process, disease progression, as well as the limitations of chest X-ray examination for diagnosing metastatic lung lesions. Analysis of the clinical case confirms the need for a comprehensive diagnostic approach, including CT to assess the prevalence of the tumor process.
