In a hybrid breed, 6 months old, sow carcass multiple air-filled vesicles were observed in several fragments of the mesentery of the small intestine and in the mesenteric lymph nodes.

This lesion is known as intestinal emphysema or Pneumatosis Cystoides intestinalis. This rare condition, detected in weaned pigs, is characterized by the presence of dilated lymphatic vessels in the mesentery and intestinal wall due to the presence of gas. The cause is unknown but it is not associated with clinical signs or poses any risk to public health.
