Lung lobe Torsion
27 April, 2021
A case with a twist
A 10- year-old schnauzer was presented with a chronic cough of months duration
- A large amount of fluid attenuating material is within the dependent aspect of the pleural space bilaterally. (Image 1)
- The right middle lung lobe is enlarged, and its bronchial lumen is focally, completely narrowed. (Image 1)
- Vesicular emphysema and a focally enlarged bronchus are also associated with this lung lobe. (Image 2)
- The right middle pulmonary parenchyma is non-contrast enhancing.
- Conclusions: Lung lobe torsion of the right middle lobe with bilateral pleural effusion
- The right middle lung lobe is the most commonly affected lobe in large breed dogs.
- Radiographic und CT characteristics: Enlargement and consolidation of the affected lung lobe, vesicular emphysema, lack of contrast enhancement, secondary pleural effusion
- Radiographs vs CT: pathognomonic focal narrowing of the bronchus on CT
