Abstract

This case report describes a capuchin monkey (Sapajus apella) that presented with bilateral paralysis and cold hind limbs. Clinical examination, including ultrasound imaging, revealed dilated cardiomyopathy and aortic thrombosis. Macroscopic, histopathological, and immunohistochemical analyses confirmed these findings. The structural myocardial changes are comparable to those of human cardiomyopathy.
