Postlymphographic cerebral lipid embolization in the vena cava superior syndrome.

A recent case of Lipiodol Ultrafluid embolism to the brain is reported. Pathogenetic concepts involving right-to-left shunts, and lympho-venous shunts with pulmonary capillary overloading are reviewed. In addition, it is suggested that a local disturbance in cerebral circulation due to a cava superior syndrome may contribute to the severe cerebral symptoms.
