Medical records of 32 cattle treated for umbilical abnormalities that had undergone ultrasonographic examination of the umbilicus followed by umbilical resection or PM examination were reviewed. 30 of the cattle were between 6 and 240 days old (mean 73 days); the remaining 2 cattle were a 3-year-old bull and a 5-year-old cow. 30 (94%) animals had external evidence of infection associated with the umbilicus. Two calves did not have external signs of infection; 1 had an abscess of the urachus and the other was found to be normal. Two-dimensional real-time ultrasonography was used to identify abnormal umbilical cord remnants. Ultrasonographic results were most reliable for the urachus, and the urachus was the commonest affected internal umbilical cord remnant. Statistical agreement between ultrasonographic and physical (surgical or PM) findings was good to excellent for all umbilical structure. Intra-abdominal adhesions were found at surgery in 47% of animals with umbilical abnormalities: however, adhesions were not detected ultrasonographically.
