Hennekam syndrome presenting as nonimmune hydrops fetalis, congenital chylothorax, and congenital pulmonary lymphangiectasia

Abstract

We report a female infant with congenital lymphedema, facial anomalies, intestinal lymphangiectasia consistent with a diagnosis of Hennekam syndrome. At birth the patient presented with severe respiratory distress due to nonimmune hydrops fetalis, a congenital chylothorax (CC), and pulmonary lymphangiectasia. Hydrops fetalis may be present in newborns with the Hennekam syndrome. Lymphoscintigraphy can be useful in explaining pleural-pulmonary involvement of this generalized lymph vessel malformation syndrome.
