Variety Range (difference between the maximum and minimum transverse diameters in percentage of the minimum diameter) was calculated for 86 lumbar lymph nodes with maximum diameter ranging between 5 mm and 19 mm at CT. The nodes were located within a group (pre- and paracaval, interaortico-caval, pre- and paraaortic) which was removed during primary lymphadenectomy for non-seminomatous testicular tumor. Most nodes were fairly rounded with a Variety Range less than 20%. There was no difference between the largest node in a metastasis group (Variety Range less than 20% in 29 out of 36) and tumor free nodes (Variety Range less than 20% in 39 out of 50). A rounded shape of lymph nodes measuring less than 20 mm on transverse CT sections was not a reliable sign of metastasis in patients with non-seminomatous testicular tumor.
对86个腰椎淋巴结计算其形态变化范围（最大横径与最小横径之差占最小直径的百分比），这些淋巴结在CT上的最大直径在5毫米至19毫米之间。这些淋巴结位于一组（腔静脉前和腔静脉旁、主动脉-腔静脉间、主动脉前和主动脉旁），在非精原细胞瘤性睾丸肿瘤的初次淋巴结清扫术中被切除。大多数淋巴结相当圆润，形态变化范围小于20%。转移组中最大的淋巴结（36个中有29个形态变化范围小于20%）与无肿瘤淋巴结（50个中有39个形态变化范围小于20%）之间没有差异。对于非精原细胞瘤性睾丸肿瘤患者，横断CT切片上直径小于20毫米的淋巴结呈圆形并非转移的可靠征象。
