A case is reported of an 8-year-old male who presented with mediastinal widening secondary to idiopathic dilatation of the superior vena cava. Roentgen signs of superior vena cava dilatation include a right, anterior, and superior location in the mediastinum, lack of tracheal deviation, and increased size on supine roentgenograms. Contrast studies to define the venous nature of such a mass can obviate thoracotomy.
