[A case of renal cell carcinoma difficult to diagnose preoperatively because of hypovascular findings].
A 35-year-old man visited our out-patient clinic with the chief complaint of macroscopic hematuria. After admission to the hospital, examinations by CT scan, renal angiography, etc. revealed a hypovascular space-occupying lesion in the right kidney, but no definite diagnosis could be made; blood findings such as accentuated alpha 2-globulin and raised LDH suggested the possibility of malignancy; and right nephrectomy was performed. In view of the preoperative X-ray findings together with postoperative pathological findings, papillary renal cell carcinoma was suspected intensively. Some discussion was made on the differentiation of lesions of hypovascular to avascular tumors and the reliability of image diagnosis based on CT scan, angiography, and other methods.
