    PROFILE
    Definition
    • Pericardial effusion is a condition involving an accumulation of fluid within the pericardial sac.
      • Relatively uncommon
      • Diffuse regional distribution aside from coccidioidomycosis (infection with Coccidioides immitis), which is regional (southwestern United States)1
    Signalment
    • Pericardial effusion occurs more commonly in large-breed dogs than smaller-breed dogs.2
      • Breeds at highest risk include golden retrievers, German shepherd dogs, brachycephalic breeds (eg, boxers, bulldogs, pugs), and cocker spaniels.2
    • According to most studies, there is a male predilection.2,3
    Asbestos exposure has been linked to mesothelioma in humans; early pathology studies suggested a possible connection in dogs, but the link is unsubstantiated.

    • Secondary to infiltrative or diffuse neoplasia
