Signs of diaphragmatic rupture on computed tomography.(TODAY'S TWO SIGNS)(Brief article)
|
The 'dependent viscera sign'
The dependent viscera sign is seen with diaphragmatic rupture when there is loss of the posterior support of the diaphragm, allowing the viscera to drop against the posterior ribs and obliterating the posterior costophrenic recess. The dependent viscera sign is said to be present on the right side if the upper one-third of the liver abuts the posterior ribs (Fig. 1) and on the left side if the stomach or bowel abuts the posterior ribs or lies posterior to the spleen.
