We report the case of an 8-year-old male Poodle dog, presenting regurgitation and chronic cough, who underwent radiographic and tomographic studies, which revealed the presence of polyostotic bone nodules of mixed radiopacity. From the imaging exams, it was possible to visualize exostosis starting from the first right rib, projecting into the thorax and causing displacement of the cranial mediastinum, with consequent esophageal and tracheal displacement. Due to neoplastic compression, the dog presented marked deviation of the cranial mediastinum, tracheal dislocation and gas dilatation of the esophagus accompanied by ventrolateral deviation and tortuosity. Based on the radiographic findings, osteochondroma (multiple cartilaginous exostosis) was suspected as the main differential diagnosis, and the diagnosis was confirmed after histopathological analysis. The rare occurrence of this disease in dogs and the atypical clinical signs in this patient stand out, signs that are unprecedented in veterinary literature. The importance of imaging and histopathological exams for diagnostic conclusion, therapeutic planning and prognosis establishment is also highlighted. The surgery was successful and there has been no return of clinical signs or tumor recurrence to date.Downloads
