Concurrent bilateral hypernephroma. Successful diagnosis and treatment of one patient

Clinically unsuspected, bilateral concurrent clear cell cancers of each kidney were identified in a patient during evaluation for acute pancreatitis. A right renal lesion was demonstrated by computerized axial tomography (CAT) scan. Promptly thereafter percutaneous transfemoral aortography was performed, identifying separate, bilateral kidney neoplasms. The surgical outcome at nineteen months postoperatively has been satisfactory.
