Intussusception involving the spiral colon in a calf

Clinical examination of a ten month old Holstein heifer with a history of colic and anorexia revealed a distended viscus in the midline and a hard, sausage-shaped mass in the right lower posterior quadrant of the abdomen. At surgery, the mass was exteriorized and found to be an intussusception of the colon into the spiral colon. The intussusception was reduced by traction and the animal made an uneventful recovery.
