Presenting Signs

Chylothorax occurs when a body fluid called chyle accumulates within the thoracic (chest) cavity. Chyle is composed of lymph (a clear tissue fluid), protein and products of fat digestion. Chylothorax develops when any pathological process blocks the flow of chyle and causes chyle to leak out of vessels into the thoracic cavity. The lymphatic vessels themselves are usually intact but dilated (a condition known as thoracic lymphangiectasia). Affected cats usually have laboured breathing, are intolerant of exercise, are lethargic, have a cough, lose weight and breathe rapidly.

Cats at Risk

Any breed can be affected, however, Oriental breeds appear to have a higher prevalence.
