Cardiomyopathy in captive African hedgehogs (Atelerix albiventris).
From 1994 to 1999, 16 captive African hedgehogs (Atelerix albiventris), from among 42 necropsy cases, were diagnosed with cardiomyopathy. The incidence of cardiomyopathy in this study population was 38%. Fourteen of 16 hedgehogs with cardiomyopathy were males and all hedgehogs were adult (>1 year old). Nine hedgehogs exhibited 1 or more of the following clinical signs before death: heart murmur, lethargy, icterus, moist rales, anorexia, dyspnea, dehydration, and weight loss. The remaining 7 hedgehogs died without premonitory clinical signs. Gross findings were cardiomegaly (6 cases), hepatomegaly (5 cases), pulmonary edema (5 cases), pulmonary congestion (4 cases), hydrothorax (3 cases), pulmonary infarct (1 case), renal infarcts (1 case), ascites (1 case), and 5 cases showed no changes. Histologic lesions were found mainly within the left ventricular myocardium and consisted primarily of myodegeneration, myonecrosis, atrophy, hypertrophy, and disarray of myofibers. All hedgehogs with cardiomyopathy had myocardial fibrosis, myocardial edema, or both. Other common histopathologic findings were acute and chronic passive congestion of the lungs, acute passive congestion of the liver, renal tubular necrosis, vascular thrombosis, splenic extramedullary hematopoiesis, and hepatic lipidosis. This is the first report of cardiomyopathy in African hedgehogs.
