The value of a fine needle aspiration biopsy for confirmation of malignancy is demonstrated in 3 cases of angiographically hypovascular renal tumors. In 2 cases ultrasound examination suggested solid lesions but in 1 case it was predominantly sonolucent. Reliable documentation in the literature indicates that the risk of spreading tumor cells and, hence, of decreasing the survival rate is negligible.
3例血管造影显示为少血管性肾肿瘤的病例证明了细针穿刺活检对确诊恶性肿瘤的价值。2例超声检查提示为实性病变，但1例主要为透声性。文献中的可靠资料表明，肿瘤细胞播散从而降低生存率的风险可忽略不计。
