Scintigraphic documentation of systemic-portal shunting.

Two unusual cases of iliac vein thrombosis are presented. They were studied with radionuclide venography of the left lower-extremity in which one of the collateral channels was the inferior mesenteric vein and showed the entire liver and lungs simultaneously. This vein does not appear to have been clearly identified with radioisotopic techniques previously.

Thoracic duct malformations. Lymphoscintigraphic diagnoses.

A patient with lower extremity lymphedema studied with lymphoscintigraphy is described. Radionuclide lymphography demonstrated several thoracic duct malformations that were confirmed by contrast lymphography.
