Intrapericardial Neoplasia in Dogs

Abstract

A retrospective study was conducted from 1,919 necropsies of dogs, and 52 cases were selected on the basis of primary or metastatic neoplasia in the pericardium, the heart base, or the myocardium. Primary intrapericardial neoplasms were more frequent than intrapericardial metastases. Hemangiosarcomas were the most frequent primary neoplasms, followed by chemodectomas. Lymphomas were the most frequent metastatic neoplasms, followed by fibrosarcomas and rhabdomyosarcomas. Other neoplasms, either primary or metastatic, occurred rarely.
