Abstract

Lymphoma is a hematopoietic neoplasm resulting from the proliferation of lymphoid cells, and can affect domestic cats of any age, sex, or breed. Among the main risk factors are infection with feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV). This report aims to describe the clinical presentation and diagnostic findings of a feline with pleural effusion secondary to lymphoma. A feline was seen at a veterinary hospital presenting with altered respiratory pattern, lethargy, and anorexia. Chest radiography revealed the presence of pleural effusion, and cytological analysis showed high cellularity with a predominance of intermediate and large lymphocytes. The combination of clinical examination, history, and imaging studies was fundamental for the diagnosis. Due to the patient's advanced clinical condition, treatment could not be initiated, highlighting the importance of a rapid and thorough assessment of respiratory signs in cats.
