  • A 7 years old, male, Afghan hound (case 1) and a 10 years old, castrated male, Pekingese (case 2) were referred with dyspnea. In case 1, thoracic radiographs showed moderate amount of pleural effusion and lobar sign in the left cranial lung lobe. Following computed tomographic (CT) examination, lung lobe torsion in left cranial lung lobe was diagnosed. In case 2, thoracic radiographs showed increased cranial lobar opacity but there was no evidence of pleural effusion. CT examination revealed an abrupt ending bronchus in the left cranial lung lobe. Based on the imaging diagnosis, left cranial lung lobectomy was performed in both cases. Case 1 showed increased lobar opacity and pleural effusion, while case 2 just showed less concrete evidence of lung lobe torsion on thoracic radiographs and marked severe chronic suppurative pneumonia was histopathologically confirmed. In conclusion, CT could be an important modality when atypical lung disease is suspicious.

  • An 11-year-old intact female miniature poodle presented with a four-month history of hemorrhagic effusion. The patient was alert on physical examination, although muffled heart sounds were noted upon auscultation of the right hemithorax. The radiographic finding was pleural effusion. Ultrasonography revealed cystic changes in both ovaries and several nodules in the liver. A refractory opacity in the right lung field, as visualized with computer tomography (CT), was diagnosed as right middle lung lobe torsion with a collapsed bronchus. Five days after diagnosis, a right fifth intercostal thoracotomy was performed to remove the right middle lung lobe; the right middle lung lobe was grossly shrunken as a result of chronic lung lobe torsion. Ovariohysterectomy was also performed. Histopathologic examination revealed papillary adenocarcinoma in both ovaries and suspected metastasized ovarian adenocarcinoma cells in the lung lobe. The patient recovered favorably and had been doing well up to two months post-surgery. However, after four months, the dog presented with respiratory difficulty. The radiographic findings were pleural effusion and collapse of the right cranial and left caudal lung lobes. Malignant cells of epithelial origin were observed in the pleural effusion. The tumor cells were suspected to be metastasized cells from the previously resected lung lobe. Although cancer treatment was recommended, the suggestion was suspended and the dog was discharged from hospital. This was a case of lung lobe torsion that had occurred because of hemorrhagic effusion due to tumor. Although ovariohysterectomy and lobectomy were performed, there was a relapse of hemorrhagic effusion because of metastasized tumor from the previously resected lung lobe.

  • A 7-year-old castrated male Pomeranian dog presented with severe goose honking cough and dyspnea. Thoracic radiographs revealed a narrowed tracheal diameter at the thoracic inlet, classified as tracheal collapse grade 4. Despite medical treatment, the dog's life-threatening airway obstruction did not improve. Subsequently, tracheal stent placement resulted in a significant improvement in respiratory condition, with no recurrence of symptoms observed during the 4-month period, except for coughing induced by excitement and anxiety. However, the patient presented with a one-week history of productive cough, exercise intolerance, and loss of appetite. Radiographs and computed tomography scans revealed torsion of the left cranial lung lobe. The patient underwent affected lung lobectomy, which involved the removal of the necrotized cranial portion and heavily congested caudal portion. Unfortunately, the patient did not recover and eventually passed away. Histopathological examination of the resected lung tissue confirmed coagulative necrosis and marked peribronchiolar edema, consistent with lung lobe torsion.

  • A four-year old, female Miniature Pinscher was presented with intermittent coughing. Thoracic radiography and ultrasonography revealed the consolidation of left cranial lung lobe surrounded by pleural effusion and the extraction of left lung lobe was performed through thoracotomy. This case has the clinical significance because lung lobe torsion was diagnosed by non-cardiac ultrasonographic examination, therefore surgical correction was performed without delay and led good outcome. Moreover, the authors believe the present case was the first report on lung lobe torsion in Miniature Pinscher dog.

  • This case study describes the imaging features of radiography and computed tomography (CT) in four small breed dogs with lung lobe torsion. The medical records, thoracic radiographs and CT images of four dogs with confirmed lung lobe torsion were retrospectively reviewed. Pleural effusion and increased lobar opacity/density were seen on all CT and thoracic radiography in all four dogs. CT revealed narrowed/collapsed bronchus in all four dogs, while this was only appreciated on one thoracic radiography. The vesicular emphysema pattern was seen on four CT but only on three radiographic examinations. The specific findings of lung lobe torsion were vesicular emphysema and a narrowed/collapsed bronchus. These findings were more easily recognized on CT than with thoracic radiographs.

  • A 9-year old, castrated male Pekingese dog weighing 6.9 kg was referred with one week history of dyspnea, depression, yellow vomiting and abdominal distension. Refractory right lung field opacity was diagnosed as spontaneous right cranial lung lobe torsion (LLT) with collapsed middle lobe on the computed tomography. Four days after diagnosis, right fourth intercostal thoracotomy was performed under propofol-remifentanil based total intravenous anesthesia (TIVA). Right cranial and middle lung lobes were twisted together in a clockwise direction. ENDOPATH-ETS-FLEX-45, an articulating endoscopic linear cutting stapler was applied at the hilus and there were no complications after resection. The patient recovered favorably and has been doing well up to one year follow up. Lung lobe torsion is an uncommon condition in small breed dogs, this case report suggests serial lung lobe torsion of cranial lobe followed by middle lobe in small breed dog, and immediately after diagnosis surgical intervention is beneficial to prevent progression of LLT. Furthermore, using self cutting stapling device and TIVA technique will be helpful for lung lobectomy in dogs.

  • Lung torsion is a very rare event that has been reported in only 9 cases in the pediatric literature but has not yet been reported in Korean infants. We present a case of lung torsion after tracheoesophageal fistula repair in an infant. Bloody secretion from the endotracheal tube and chest radiographs and computed tomographic scan results indicated lung torsion. Emergency exploration indicated $180^{\circ}$ torsion of the right upper lobe (RUL) and right middle lobe (RML). After detorsion of both lobes, some improvement in the RUL color was observed, but the color change in the RML could not be determined. Although viability of the RML could not be proven, pexy was performed for both the lobes. Despite reoperation, clinical signs and symptoms did not improve. The bronchoscopy revealed a patent airway in the RUL but not in the RML. Finally, the RML was surgically removed. The patient was discharged on the 42nd day after birth.

  • A 4-year-old intact male, Maltese dog weighing 2.2 kg was presented for evaluation of tachypnea and hyperthermia. On initial evaluation, the dog was dyspneic, but alert and responsive. Muffled heart sound was noted with auscultation of the right hemithorax. The radiographic findings were consolidation of the right middle lung lobe, pleural effusion, and abdominal fluid accumulation. Thoracic computed tomography confirmed a contrast-enhancing mass within the right middle lung lobe. Surgical exploration of the thoracic cavity was performed using a right fifth intercostal thoracotomy. Examination of the right lung lobe revealed $360^{\circ}C$ torsion of the right middle lung lobe at the level of the hilus, in a clockwise direction. Lung lobectomy was performed using a thoracoabdominal stapling device with 2.5-mm vascular staples. Full-thickness intestinal biopsy by exploratory laparotomy was taken from the jejunum for histological assessment. Histopathologic examination of the full-thickness intestinal biopsy revealed distended lacteal located within the submucosa of the jejunum. Intestinal lymphangiectasia was resolved with prednisone and low fat diets. Subsequent communication with the owner revealed that the patient was in good health 6 months post-discharge.

  • The remaining lung infarction is a rare but life-threatening complication after a thoracic operation and trauma. We report a case of this rare complication after the left upper lobectomy due to pulmonary aspergilloma. The infarction of the remaining left lower lobe occurred due to kinking of the pulmonary vessels after the left upper lobectomy and the completion pneumonectomy was performed in the post-operative second day. Therefore, prompt diagnosis and treatment may be necessary to prevent morbidity and mortality associated with pulmonary infarction from torsion of pulmonary artery and vein.
