Infraphrenic collaterals in malignant superior vena cava obstruction.
We present three cases of malignant superior vena cava obstruction demonstrating infraphrenic venous collaterals, one of which showed intense focal hepatic enhancement on computed tomographic scan. Infraphrenic venous collaterals and focal liver enhancement are uncommon but specific computed tomographic features of superior vena cava obstruction.
