Arteriographic Manifestations of Ganglioneuromas.

The angiographic finding in four cases of ganglioneuroma are described. In all four cases a large vascular mass was demonstrated angiographically. The vessels supplying the tumors varied, depending on the location of the mass. Stretching and displacement of adjacent opacified vessels helped define the extent of the tumor. Abundant neovascularity was present with serpiginous vessels tending to cluster in nodular areas, with adjacent avascular areas.
