Two Cases of Cats with Granulomatous Pneumonia Showing Different Outcomes of Treatment

Abstract

A diagnosis of granulomatous pneumonia was made in two cats. Case 1 was an 8-year-old castrated mixed-breed cat which was referred to our clinic for a check-up. Thoracic radiography showed a mass, which was removed surgically. The cat has been well without recurrence after surgery. Case 2 was a 7-year-old castrated mixed-breed cat with a history of respiratory distress when excited. Radiography showed multiple masses in the lung, and further examinations such as computed tomography and fine-needle aspiration/clonal expansion were done. Based on these, we diagnosed the disease tentatively as well-differentiated lymphoma, and started chemotherapy, but it was ineffective. By biopsy, the disease was diagnosed as granulomatous pneumonia. After that, we could only treat the cat with prednisolone and cyclosporine.
