The authors report two cases in which ultrasound-guided lymph node puncture with administration of oil contrast agent, so-called intranodal lymphography (lymphangiography), was performed. One patient was treated for chylous ascites, the other patient presented for right-sided chylothorax.
The reason for lymphangiography was to demonstrate lymphatic extravasation and to induce aseptic inflammation leading to fibrosis with subsequent cessation of lymph secretion into the pleural or abdominal cavity. Intranodal lymphography replaces conventional bipedal lymphography because it reduces the duration of the examination and does not require difficult preparation and insertion of a needle into lymphatic vessel at the dorsum ofthefoot.
