Abstract:
Pericardial mesothelioma is a rare neoplasm in dogs. This report describes a case of pericardial mesothelioma in a 13-year-old Shih Tzu that presented with a clinical history of dyspnea. Hemorrhagic pericardial effusion and chylous pleural effusion with reactive mesothelial cells were identified by radiograph and cytology. Necropsy revealed multiple round nodules throughout the pericardium and regional lymph nodes in addition to chylothorax. Histopathology revealed invasive neoplasm on the pericardial surface with metastasis to the lymph nodes. The neoplastic cells were immunopositive to both cytokeratin and vimentin. Diagnosis of pericardial mesothelioma with regional lymph node metastasis was made.
