Ultrasound, Angiography and Fine Needle Aspiration Biopsy in Diagnosis of Renal Neoplasms

The diagnostic approach to a renal mass including ultrasound, angiography and fine needle aspiration biopsy is reviewed on the basis of 23 cases. The value of the combination of these methods is emphasized especially in tumors which appear without echoes at ultrasround and avascular-hypovascular at angiography. The findings are correlated and some differential diagnostic problems discussed as well as the possible risk of spreading tumor cells at fine needle aspiration biopsy.
