[Acute adult respiratory distress syndrome after lymphography]

Pulmonary complications of lymphography are usually described as radiological infiltrates without clinical symptoms. However, a case is here reported of an adult respiratory distress syndrome occurring after lymphography in a 60 year old female lymphoma patient. Pulmonary oedema developed within 48 h; haemodynamic study showed a normal capillary wedge pressure. The patient died from intractable low cardiac output within 24 h. Post-mortem examination showed pulmonary lymphocytic infiltration and multiple fat emboli. The lack of lymphatic drainage was probably responsible for the intravascular passage of lipid-soluble contrast medium, this giving endothelial lesions. In such patients with preexisting lung disease or pulmonary involvement in haematological disease, lymphography has to be considered carefully.
