Ultrasound guided aspiration biopsy of renal mass lesions was performed in 56 patients in whom renal cell carcinoma could not be excluded due to equivocal imaging results. Cytology showed non-malignant mesenchymal cells consistent with angiomyolipoma in 12 patients. In 5 of these patients the diagnosis was ensured by open biopsy. No nephrectomy was performed. In 6 of the 7 patients not operated upon the tumours remained unchanged with no evidence of malignancy during a 3-36 months' follow-up period. Aspiration biopsy is an easy and safe method for diagnosing renal angiomyolipoma in cases where computed tomography is not diagnostic for this disease.
对56例因影像学结果不明确而无法排除肾细胞癌的患者进行了超声引导下肾肿块病变穿刺活检。细胞学检查显示，12例患者为非恶性间充质细胞，符合血管平滑肌脂肪瘤。其中5例患者通过开放活检确诊。未进行肾切除术。在7例未接受手术的患者中，有6例在3至36个月的随访期内肿瘤保持不变，无恶性证据。在计算机断层扫描对该病无法诊断的情况下，穿刺活检是诊断肾血管平滑肌脂肪瘤的一种简单、安全的方法。
