SummaryThis cases series of 13 pugs with lung lobe torsion (LLT) is the largest case series of pugs in the literature and the first to compare dogs presenting before and after 12 months of age. Similar to previous case series, the median age of pugs with LLT was 17 months; however six dogs were under 12 months of age (3 of 13 were 11–13 weeks at presentation). There were no differences between the dogs that presented younger or older than 12 months old with respect to sex, neuter status, lung lobe affected, duration and nature of clinical signs, time alive after discharge, and complications. The juvenile onset may suggest that some dogs are inherently at risk of LLT. This is intriguing and important as LLT may not be an intuitive diagnosis in a juvenile brachycephalic animal, and practitioners should be aware of this unusual presentation.

“…In dogs, in which the condition is better documented, predisposition for lung lobe torsion is related to younger and middle-aged, large breed, deep-chested animals; the right middle lobe (RML) is most frequently affected (Hofeling et al 2004;D'Anjou et al 2005). However, it also occurs in small breeds, in which torsion is generally spontaneous and overrepresented in the left cranial lobe (Rooney et al 2001;Murphy and Brisson 2006). Chronic presentation of torsion as well as concurrent torsions have been reported (White and Corzo-Menendez 2000;Murphy and Brisson 2006).…”

ABSTRACT:A three-year-old male British shorthair cat that had exhibited progressive lethargy and intermittent dyspnoea for 14 days was referred for evaluation of acute respiratory deterioration. Clinical findings included rapid and shallow breathing, pale mucous membranes, sound suppression on the right side, and a subcutaneous haematoma in the right epigastric area. Serum biochemistry analysis showed leukocytosis and thrombocytosis. Radiographs revealed hydropneumothorax, a broken eighth right rib, atelectatic right cranial lung lobe (RCrL), and consolidation of the right middle lobe (RML). Doppler examination revealed sonographic changes in the echotexture of both lobes and venous flow was absent in the twisted RML. Furthermore, bronchoscopy showed proximal narrowing of the cat's RML bronchus. Exploratory surgery via medial sternotomy confirmed torsion of the RML and identified deteriorated gas-containing lesions in the collapsed RCrL. Both lung lobes were removed by standard lobectomy, and postoperative recovery was without major complications. Histopathological examination diagnosed multiple bullae and blebs, with significant subpleural haemorrhages in the atelectatic RCrL, whereas tissue congestion with haemorrhages, necrosis, and thrombosis typical for lung lobe torsion were observed in the RML. No other underlying aetiology was apparent. Two months post-operatively, the cat presented with similar acute onset of dyspnoea and spontaneous pneumothorax and was euthanised at the owner's request. The autopsy revealed identical new emphysematous changes in the contra-lateral lung lobes that had been absent at the time of surgery. Emphysematous lesions, regardless of their origin, should be considered in the etiopathology of lung lobe torsion.

“…Lung lobe torsion (LLT) is a rare disorder in veterinary medicine which has been described in dogs and cats, and also in humans (Moses, 1980;Johnston et al, 1984;Fossum et al, 1986;Gallagher 1993;Gelzer et al, 1997;Dye et al, 1998;Neath et al, 2000;Rooney et al, 2001;White and Corzo-Menendez, 2001;Spranklin et al, 2003;Hofeling et al, 2004;Della Santa et al, 2006;Murphy and Brisson, 2006;Fossum, 2007). In LLT a lung lobe is rotated around its long axis, causing physical displacement and the twisting of the lobe around its bronchovascular pedicle (Gallagher, 1993); the consequence of an increase in lobar pressure results in pulmonary consolidation and pleural effusion (Neath et al, 2000).…”

“…Surgical treatment is required for treatment of LTT; a thoracotomic approach provides a good visualization of the pathological lobe and facilitates its removal (Neath et al, 2000;White and Corzo-Menendez, 2001;Murphy and Brisson, 2006;Fossum, 2007).…”

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 (

Evaluation of lung lobe torsion in Pugs: 7 cases (1991–2004)

Abstract: Results indicated that young male Pugs may be predisposed to developing spontaneous LLT. The prognosis for survival and resolution of clinical signs in Pugs with LLT appeared to be excellent. Factors contributing to the development of LLT in Pugs are not known.
