title: Ataxia in a Welsh cob filly due to a venous malformation in the thoracic spinal cord.
abstract: An 8-month old Welsh Cob filly had shown progressive ataxia of the hindquarters since about 3 months of age. Autopsy revealed a venous malformation resulting in malacia in the ninth thoracic segment of the spinal cord. It is proposed that the tissue destruction associated with this congenital lesion gave rise to the ataxia.
