“…1,2,4,5 Patients with lung lobe torsion typically present with respiratory signs such as coughing, hemoptysis, dyspnea, and reduced heart and lung sounds on auscultation. [1][2][3][4][5]8,12 Lethargy, anorexia, weight loss, and pyrexia have also been recognized in affected patients. 1,2,4,5,8 Serum biochemical changes are generally non-specific and hematological alterations may include a neutrophilia and anemia.…”

Case summary: A 7-week-old, intact female Pug was referred with an acute history of expiratory dyspnea, tachypnea, and pyrexia. Radiologic evaluation revealed bilateral pleural effusion and a poorly demarcated area of soft tissue opacity cranial to the heart. The presence of air bronchograms in the cranial lung lobes suggested alveolar parenchymal pathology consistent with pulmonary edema, congestion, or cellular infiltration. Exploratory thoracotomy revealed a segmental torsion of the left cranial lung lobe. The affected lobe was removed and the puppy recovered uneventfully. Unique information: Lung lobe torsion tends to occur more frequently in mature large breed dogs at a mean age of 3 years. The age, breed, and segmental nature of the torsion in the reported case are contrary to most of the previously documented cases of lung lobe torsion. To the authors' knowledge, this is the first report of lung lobe torsion in a 7-week-old dog. (J Vet Emerg Crit Care 2006; 16(3): 215-218)

“…The radiographic and ultrasonographic findings with LLT have been well described in the dog and cat (Brown and Zontine 1976, Siems and others 1998, d’Anjou and others 2005, Della Santa and others 2006). However, the findings are sometimes non‐specific and do not always discriminate between surgical and non‐surgical disease (d’Anjou and others 2005).…”

This report describes the imaging features of radiography, computed tomography and virtual bronchoscopy in dogs and cats with lung lobe torsions. The medical records, thoracic radiographs and computed tomography images of four dogs and two cats with confirmed lung lobe torsions were retrospectively reviewed. Computed tomography with virtual bronchoscopy showed bronchial narrowing, collapse or occlusion in all six animals, while this was only appreciated on one radiographic examination. A tapering terminating angle of the air-filled bronchus proximal or distal to the collapsed region was seen only on computed tomography and virtual bronchoscopy in all six animals. The vesicular emphysema pattern typical of lung lobe torsion was seen on three computed tomographies but only on one radiographic examination. The lung lobe torsion-specific findings of vesicular emphysema and a proximally narrowed or occluded bronchus were more easily recognised on computed tomography and virtual bronchoscopy than with radiographs. Computed tomography slices acquired through the bronchus and lung lobe of interest in a cat or dog with possible lung lobe torsion can be reformatted into virtual bronchoscopic images that can be utilised along with computed tomography to help make a more definitive preoperative diagnosis.

“…In our case, similar to what has been already documented, radiological radiographic and ultrasonographic findings were not specific and broncoscopy was preferred in order to evaluate the hemoptysis which could be associated with other bronchial pathologies (Siems et al, 1998).…”

“…Radiography and ultrasonography are the initial diagnostic imaging techniques used to make a correct diagnosis (Siems et al, 1998;D'anjou et al, 2005;Della Santa et al, 2006). Radiographic findings, such as lobar consolidation or increased opacity of the thorax, are sometimes non-specific and other diagnostic techniques are required (D'anjou et al, 2005;Seiler et al, 2008).…”

Lung lobe torsion (LLT) is an uncommon pathology in small animal practice. In large breed dogs LLT effects are localized mainly to the middle lobe of the right lung. This report describes a case of left cranial lung torsion in a Bernese Mountain dog: the patient was referred with a two-day history of asthenia, anorexia, dyspnea and haemoptysis. No trauma was reported. Physical examination showed the presence of bilateral pleural effusion confirmed by radiography and ultrasonography. Broncoscopy revealed that the left cranial lobe appeared to be compressed laterally with complete occlusion of the lumen. Thoracoscopy was performed to exclude other pathologies of the pleural space. The pathological lobe was removed. Histological examination revealed aspects consistent with lung lobe torsion. Clinical follow up carried out after three months showed a normal clinical course.Keywords: lung; lobe; torsion; Bernese; dog Lung lobe torsion (LLT) is a rare disorder in veterinary medicine which has been described in dogs and cats, and also in humans (
