The aim of this report was to present a clinical case and diagnostics of intrathoracic bone cyst as well as successful outcome of the surgical treatment in a male, 3-year-old West Highland White Terrier dog, weighing 6.9 kg. The dog was admitted in a very poor condition with clinical signs of severe dyspnoea that developed during about one month period of time before admission to our clinic. The dog underwent physical examination and further examinations including radiological examination which revealed a radiopaque mass formation in the cranial mediastinum. Ultrasonographic examination showed the presence of fluid; following thoracentesis revealed pseudochylous fluid. The bone cyst was surgically removed and more than 10 months after surgery the dog’s health was very good without any difficulties. Bone cysts in dogs are infrequent; this was the first case at our clinic and presented a successful treatment.
