Correlation of selective angiography and pathology in cavernous hemangioma of the kidney.

Angiographic and pathologic findings are presented and correlated in a case of renal cavernous hemangioma, and considered in relation to 3 other cases published previously. A normal angiogram does not exclude a cavernous hemangioma. Those tumors with a large arterial component may be demonstrated in the arterial phase of the angiogram. A discrete tumor may show an area of hypovascularity by displacing normal renal tissue but a diffuse cavernous hemangioma is likely to yield a normal angiogram.
