Pheochromocytoma
Neovascularity
The angiogram of the right inferior adrenal artery shows mass that is characterised by hypervascularity and neovascularity (a). Image b is a magnified view of the inferior part of the mass that highlights the neovascularity that is characterized by vessels that have a non geometric pattern with vessels branching in odd directions and non progressive change in size, unlike the tree like branching that occurs in normal structures. This mass was diagnosed as a pheochromocytoma. Angiography is not safely performed in patients with pheochromocytoma since a crisis can be precipitated by the contrast. This case originates from an era prior to sophisticated imaging and biochemical evaluation
