Bottom Line: Lung lobe torsion is rare but life-threatening condition in the dog.Thoracic radiographs and conventional ultrasonography cannot be conclusive for the diagnosis, and computed tomography is useful but is limited by cost and availability.Contrast-enhanced ultrasonography showed the absence or reduction of pulmonary vascularization secondary to twisting of the lung lobe around its bronchovascular pedicle in all three dogs.

ABSTRACT
Lung lobe torsion is rare but life-threatening condition in the dog. Thoracic radiographs and conventional ultrasonography cannot be conclusive for the diagnosis, and computed tomography is useful but is limited by cost and availability. This report describes the findings of contrast-enhanced ultrasonography in 3 dogs with lung lobe torsion. Contrast-enhanced ultrasonography showed the absence or reduction of pulmonary vascularization secondary to twisting of the lung lobe around its bronchovascular pedicle in all three dogs. Moreover, contrast-enhanced ultrasonography distinguished partial pulmonary atelectasis from a lung lobe torsion. These preliminary results suggest that contrast-enhanced ultrasonography can improve the accuracy of conventional ultrasonography for detection of pulmonary blood flow compromise in dogs with lung lobe torsion.

Lung lobe torsion in case 3. B-mode ultrasound image (A) showing consolidated lung lobe(*). Air bronchogram (thin arrow) within the suspected lung lobe is evident. Liver (**)can be seen to the right of the image. Contrast harmonic mode ultrasound image of thesame scan before the injection of the contrast agent (B). Contrast-enhanced ultrasoundimages showing enhanced vessels inside the lung lobe (arrows) after 25 sec frominjection of the contrast agent (C). Vascular enhancement (arrowheads) can be seenwithin the liver (C).
