Background: Pyothorax is characterized by the accumulation of septic purulent fluid within the pleural space. Most of the times, it is the true identified infection way in only 2 to 22% of dog cases. Reports show that the most common cause is the migration of grass edges and plant materials, mainly in regions of California, USA. The current study reports an unusual case of a Cassia fistula pod (Brazilian Acácia Imperial), of around 10x3 cm long, causing chronic Pyothorax in a Border Collie female dog. Case: It was admitted in a Teaching Veterinary Hospital a 2-year-old female Border Collie, weighing 16.5 kg. The complaint was producing of severe cough, dyspnoea, hyporexia and loss of weight in the past three months. The animal could have been horse-kicked, as it is used to herding. In the physical examination, it was detected bilateral thick lung crepitations, more evident in the ventral skull area, dyspnoea, tachypnea, fever, splenomegaly and low body condition score (3/9). The laboratory tests revealed nonregenerative anemia and leukemoid reaction. The chest x-ray showed intense pulmonary opacification and free fluids in the pleural space along with a heterogenic cylindrical image of the mixed radiopacity. This image was then confirmed as the intrathoracic foreing body by the use of a computerized tomography. In this exam it was also possible to observe the damage of part of the middle and inferior right lung lobe. The cytology of the pleural effusion found mixed inflammation and coccoid bacteria, and the microbiological culture Streptococcus sp., and Escherichia coli. The dog underwent thoracotomy in order to remove the foreign body, which was later identified as being a Cassia fistula pod (Brazilian Acácia Imperial), of around 10x3 cm long. Due to the intense lung damage, a right pneumonectomy was required. After 30 days the animal was fully recovered.[...](AU)
