A 5 year old male castrated Shiba Inu dog presented to Cornell’s Hospital for Animals with previously diagnosed chylothorax. The patient had an increased respiratory rate and effort and was reported to be more lethargic than usual. Computed tomography (CT) was performed to evaluate the thoracic cavity and torsion of the right middle lung lobe was identified. Following CT, a right middle lung lobe torsion was identified along with pleural effusion and pneumothorax. The patient underwent an intercostal thoracotomy and lung lobectomy of the right middle and caudal lung lobes, and placement of a PleuralPort thoracic drain. Complications that occurred post-operatively included persistent chylothorax and pneumothorax casued by iatrogenic trauma to an adjacent lung lobe. A second intercostal thoracotomy and right cranial lung lobectomy were performed to correct the pneumothorax. The patient was discharged to the care of his owner with dereased but residual chylothorax as a continuous complication.
