==Description==
'''Lymphangiectasia''' is characterised by dilation and dysfunction of the lymphatic vessels of the intestines. Consequently, protein rich lymph leaks into the intestinal lumen, causing a protein-losing enteropathy and severe lipid malabsorption. It is relatively common in dogs but rare in cats.
Lymphangiectasia can be classified as primary or secondary. '''Primary lymphangiectasia''' may form part of of a localised or a more widespread lymphatic abnormality. '''Secondary lymphangiectasia''' is the result of lymphatic obstruction. The obstruction may be caused by:
*inflammation, neoplastic infiltration o fibrosis
*thoracic duct obstruction
*right sided cardiac failure
*caval obstruction
*hepatic disease
Lymphagiectasia often accompanies a lipogranulomatous inflammation, but it is not clear which is the primary event. Lymphangitis can cause lymphatic obstruction but the leakage of lymph can cause a granuloma to form.
