داء الأمعاء الالتهابي
The most common cause of lymphangiectasia was congenital malformation of the lymphatics. Secondary lymphangiectasia may be caused by granulomas or cancer causing lymphatic obstruction, or increased central venous pressure (CVP) causing abnormal lymph drainage. Increased CVP can be caused by pericarditis or right-sided heart failure. Inflammatory bowel disease can also lead to inflammation of the lymphatics and lymphangiectasia through migration of inflammatory cells through the lymphatics.
