In acute calssical swine fever, pathological changes are most typically haemorrhagic. Haemorrhages are seen in the lymph nodes, which are also swollen and oedematous. Appearance of haemorrhages in the kidney can vary from petechiae (giving a "turkey egg" kidney) to ecchymoses, and petechiae can also be observed in the larynx, bladder and heart as well as on serosal surfaced. A non-purulent encephalitis is sometimes seen.
