Traumatic pericarditis in cattle

This disease develops when sharp foreign materials such as needles and wire perforate the second stomach, penetrate the diaphragm, and reached the pericardium. Initially, serum exduates and is mixed with fibrin clots. Subsequently, the lesion becomes purulent, and the pericardium is thickened during a long course, becoming adherent to the heart or diaphragm. Continuous perforation by the foreign material causes fistulation in its passage, and perforation also occurs in the heart. In addition, purulent lesions form in the pulmonary pleura and sometimes in the liver and spleen.
