Enquiry about changes in spleen size and color in a pig carcass.

Splenomegaly and evidences of peritonitis were observed in a mixed breed pig.

Histopathological study showed a marked hyperemia with extensive coagulation necrosis of the splenic parenchyma; regional lymphnodes were filled up with blood and fibrin and the omentum showed hemorrhages, edema and fibrinous material deposits in its surface.

These lesions are highly compatible with a splenic torsion which is relatively common in swine although usually more common in sows than in fattening animals.

Color changes can be observed in the parenchyma corresponding to areas of coagulation necrosis and darker hemorrhagic areas.

Enlarged spleen due to passive congestion and inflammation of the omentum.
