The Present Status of the Diagnosis of Renal Tumors*
When one considers the high rate of mortality associated with renal tumors and the advanced stage of their development before a diagnosis is made, and that metastatic lesions are often the first sign of the disease, one is at once impressed with the importance of any new diagnostic developments in this field. A correlation of such information has been my aim in this presentation.
First of all, it is assumed that at the present time a roentgenologist undertaking the examination of a patient suspected of having a renal tumor is a capable clinician who is familiar with the history, symptoms and course of such lesions, together with the morphology, pathology and possibilities of behavior at any stage of their course and also with the pathologic conditions of the kidney and surrounding areas which must be taken into consideration in making a differential diagnosis. Many times by a process of elimination of possible causes of the symptoms a diagnosis of renal tumor may be made when a direct attempt at making such a diagnosis would fail.
The recent developments in the diagnosis of kidney tumors reported in the literature have been rather limited to case reports and to the emphasis of complications encountered accompanying such lesions. I have attempted to abstract from these reports such information as may be of aid to the roentgenologist in reporting his findings.
In summing up a paper on “Tumors of the Renal Pelvis,” MacKenzie and Ratner13 conclude:
“The disease is very often wrongly diagnosed and. . .
