| Abstract: | The clinical and imaging features of twelve dogs with vacuum phenomena are reviewed. Gas accumulations were identified as radiolucent areas within the intervertebral discs of the cervical, thoracic, and lumber spine, the joint spaces in the sternum, and the shoulder joint. The intervertebral and sternal gas accumulations were associated with other radiographic features of degeneration such as endplate sclerosis and spondylosis. Gas attributable to vacuum phenomenon has not been previously described in the sternum of animals. Abnormal radiographic positioning stresses or instability were through to be responsible for the focal gas accumulations. |
