Pneumatosis cystoides intestinalis
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.

I have found few cases at slaughter pigs. It is a very rare condition that one can find at slaughterhouse. Until now, there’s not a causative agent to cause this condition. Some say that Clostridium species can be involved in the pathogenesis of the peumatosis, but there’s not any light about this. Is there anyone with enough courage to investigate the real cause?

Twice, I read one US paper, epi study, number of examen animals was huge…and as i remember lesion is related with trichuris infection…if i remember correct. All animals had trichuris infection background.
Dear All,
After the process of cleaning of the body/carcass, we think because of the too hot water and/or too hot gas-fire, in thin pigs we sometimes have found this condition.
Congratulation and Good luck, Laszlo
