The histopathologic findings at retroperitoneal lymph node excision in 29 patients with a non-seminomatous germ cell tumour were compared with the findings at preoperative computed tomography, ultrasound and lymphography. The possibilities of detecting retroperitoneal metastases are somewhat greater with computed tomography than with lymphography. In the present material ultrasound was less reliable than computed tomography for demonstrating small metastases. At postoperative follow-up, in more than half of the patients computed tomography could not discriminate benign postoperative abnormalities from recurrent tumours. Ultrasound seemed to be a more reliable method for postoperative evaluation of the retroperitoneal space.
对29例非精原细胞性生殖细胞瘤患者行腹膜后淋巴结切除的组织病理学结果，与术前计算机断层扫描（CT）、超声及淋巴造影结果进行了比较。CT检测腹膜后转移灶的可能性比淋巴造影略大。在本研究资料中，超声在显示小转移灶方面不如CT可靠。术后随访时，超过半数患者的CT无法区分良性术后异常与复发肿瘤。超声似乎是术后评估腹膜后间隙更可靠的方法。
