Background: Chylothorax in cats represents a challenge due to the possibility of involvement of multiple etiologies and the harmful consequences resulting of the presence of the chylous effusion in the thorax. The causes include neoplasms in the thoracic cavity, heart disease and thoracic injuries. It is imperative that clinical nutritional and therapeutic and / or surgical management be immediate and directed to the treatment of the cause. The objective of this work was to report a case of idiopathic chylothorax in a domestic cat solved through surgical intervention and dietary maintenance applied.Case: A 4-year-old male cat, fed with diet for the age range of adult cats, was attended at the Veterinary Hospital of the Federal Rural University of Rio de Janeiro (HV - UFRRJ), with clinical complaint of difficulty breathing, inappetence, prostration and weight loss. In the clinical examination was verified intense tachypnea, presence of heart murmur, normocorated mucosae, dehydration 7%. The animal was sedated to be submitted to radiographic examination of the thorax with pethidine and midazolam. Thoracic radiographs on the lateral, ventral-dorsal and orthostatic positions were realized and severe pleural effusion was observed in both hemitorax with drainage of 180 mL of lactescent fluid from the right hemithorax and 120 mL of left hemithorax liquid. Through analysis of cavity liquids the effusion was classified as chylous effusion. The hemogram showed a neutrophilic leukocytosis. Serum cholesterol and triglyceride concentrations (28 mg/ dL and 43 mg/dL, respectively) were lower than the concentrations of the cavity liquid (67 mg/dL and 722 mg/dL, respectively). Ultrasound examination revealed no mass in the thoracic cavity and no changes in the pulmonary parenchyma. The echocardiographic examination was also performed and did not reveal any cardiac alterations.[...](AU)
