A nine-year-old Holstein cow that developed recurrent ruminal tympany and an abnormal forelimb gait and posture ultimately became recumbent and unable to rise, and was euthanased. A postmortem examination demonstrated numerous schwannomas affecting peripheral nerves and several thoracic and abdominal viscera.
