title: Problems in the diagnosis of adrenal tumors.
abstract: The angiographic findings of cortical nodular hyperplasia, adenolipoma, and intracaval extension of recurrent pheochromocytoma were correlated with the pathological findings. Adenolipoma was angiographically similar to other adrenal neoplasms, adding difficulties to its differential diagnosis. Two cases of cortical nodular hyperplasia showed possibly pathognomonic patterns of discrete vascular cortical accumulations of contrast media which represent capillary malformations within the hyperplastic nodules. Intracaval extension of recurrent pheochromocytoma was found to be similar to other tumors which invade veins.
