title: The angiographic appearance of benign renal oxyphilic adenoma.
abstract: Four cases of oxyphilic cortical renal adenomas identified by angiography are described. A suggestive angiographic appearance is outlined for adenomas limited to the cortex: avascularity or hypovascularity; renal vessels splayed and stretched around tumor base; faint parenchymal blush during nephrograpm phase; and tumor well marginated, appearing to arise from the renal cortex. Masses that fulfill the above criteria are adequately treated with excisional biopsy if frozen section confirms their benignity.
