Intrapericardial neoplasia in dogs

A retrospective study was conducted from 1,919 necropsies of dogs, and 52 c ases were selected on the basis of primary or metastatic neoplasia in the p ericardium, the heart base, or the myocardium. Primary intrapericardial neo plasms were more frequent than intrapericardial metastases. Hemangiosarcoma s were the most frequent primary neoplasms, followed by chemodectomas. Lymp homas were the most frequent metastatic neoplasms, followed by fibrosarcoma s and rhabdomyosarcomas. Other neoplasms, either primary or metastatic, occ urred rarely.
