The liver showed multiple well-demarcated areas with yellowish discoloration in one of its lobes,.<\/p>\n
Histopathologically the lesion in the thoracic cavity was classified as a chronic fibrinopurulent abscessing pneumonia<\/strong> of bacterial<\/strong> origin with concomitant reactive pleural involvement. Although microbiological culture could not determine the ultimate ethiology, we ruled out it consisted of a case of contagious bovine pleuropneumonia (Mycoplasma mycoides<\/em>) since usually this presents with sequestration, more severe and extensive lesions, predominant location in the caudal lobes and typically abcessing character. The lesion may also be compatible with chronic Mycoplasma bovis<\/em> infection and even aspiration pneumonia (due to incipient gangrenous character of the necrosis).<\/p>\n The liver lesion consisted of a multifocal hepatic lipidosis without pathological relevance or apparent relation to the lesions of the thoracic cavity. Macroscopically hepatic tissue necrosis should be included in the differential.<\/p>\n The cow was dehydrated and cachectic at its entry into the slaughterhouse showed depression and had difficulty walking.<\/p><\/div>\n![\"The](\"https:\/\/sesc.cat\/wp-content\/uploads\/2013\/03\/SESC-015-13-4.jpg\")
