Case Study

CT – Left-sided chronic diaphragmatic rupture in a 6 year old FS chihuahua mix

This 6 year old FS Chihuahua mix dog presented for pre-surgical evaluation of a chronic diaphragmatic hernia

Image Interpretation

CT of the thorax and abdomen – The spleen, stomach, omentum, part of the liver, pancreas, gallbladder and small intestine are herniated into the left hemithorax through a large mainly left-sided diaphragmatic defect. The mass effect of the herniated organs leads to a right-sided mediastinal shift with deviation of the heart and compression atelectasis of the left caudal lung lobe. Generalized mid bronchiectasia is noted and likely to be a function of the breathhold technique. The organs of the urinary tract, part of the liver and intestine are left within the abdomen. The abdominal wall is tucked up.

DX

left sided diaphragmatic rupture

Outcome

At the time of the examination no differential perfusion of the liver or splenic parenchyma was noted and there was no evidence of gastric dilation which are possible signs of organ incarceration. However, elective surgery should be considered as spontaneous organ incarceration is a possibly fatal complication of diaphragmatic rupture and is commonly associated with presentation as an emergency case. The anatomical reconstruction of the diaphragm may be complicated by cicatricial retraction of the ruptured diaphragm
