Two and a half year old, tight abdominal distention for 2 weeks. Could not walk well with extra weight but ate and drank small amounts regularly. Should have died if egg peritonitis but did not. Did an autopsy this AM. Removed from the vent/abdomen area a 6"x4" blob of what appeared to be an unattached chunk of layers of cooked chicken. all other internal organs seemed normal behind the blob but went no further. Hopefully 3 pictures will show up. What is it???
