“…In dogs affected by bacterial pericarditis, a combination of exploratory surgery, pericardectomy and antimicrobial therapy is advocated. 11,12 Eradication of the source of the infection is imperative and surgical exploration is indicated in cases that have failed medical management or have suspected abscessation identified on diagnostic imaging. Consequently, advanced imaging, exploratory surgery and pericardectomy could be advised in affected cats, although, interestingly, complete recovery has been reported with antibiotics alone in previous cases and the cat reported here.…”

Case summaryA 4-year-old male neutered domestic shorthair cat was presented to the Oregon State University cardiology service for suspected pericardial effusion. Cardiac tamponade was documented and pericardiocentesis yielded purulent fluid with cytologic results supportive of bacterial pericarditis. The microbial population consisted of Pasteurella multocida, Actinomyces canis, Fusobacterium and Bacteroides species. Conservative management was elected consisting of intravenous antibiotic therapy with ampicillin sodium/sulbactam sodium and metronidazole for 48 h followed by 4 weeks of oral antibiotics. Re-examination 3 months after the initial incident indicated no recurrence of effusion and the cat remained free of clinical signs 2 years after presentation.Relevance and novel informationBacterial pericarditis is a rare cause of pericardial effusion in cats. Growth of P multocida, A canis, Fusobacterium and Bacteroides species has not previously been documented in feline septic pericarditis. Conservative management with broad-spectrum antibiotics may be considered when further diagnostic imaging or exploratory surgery to search for a primary nidus of infection is not feasible or elected.

A case of spontaneous purulent granulomatous pericarditis in a beagle

The present report describes a case of spontaneous purulent granulomatous pericarditis in a 16-month-old beagle. A gross necropsy revealed pericardial effusion and multiple nodules on the surface of the heart and around the aorta adjacent to the heart. The cut surface of these nodules was solid and white in color, containing partially yellowish white regions. Microscopically, granulomatous inflammation characterized by central necrotic cellular debris surrounded by neutrophils, macrophages, lymphocytes, plasma cells, fibroblasts and collagen fibers was observed in the epicardium. In addition, degeneration or necrosis of the arterial wall with inflammation was observed in the nodules. No gross and histological findings were observed in any organs other than the heart. Bacteria and fungi were not detected by Periodic acid-Schiff staining, Gram-Hucker staining and Ziehl-Neelsen staining. Based on these findings, the dog was diagnosed as having purulent granulomatous pericarditis. Purulent pericarditis is usually caused by pyogenic bacterial or fungus infections; however, no changes indicating a possible infection were observed in this case. In cases with spontaneous vascular changes, such as idiopathic canine polyarteritis or beagle pain syndrome, epicarditis could be secondarily caused by vascular lesions. Since this case showed different pathological features from those of spontaneous vascular changes, the pathogenesis may be different and remains unclear. To the best of our knowledge, this is the first report describing purulent pericarditis in beagles. Our case report is expected to be useful information that can be used as cardiac background findings for evaluating heart lesions in preclinical toxicology studies performed in beagles.
