In order to determine whether real-time sonography or contrast-enhanced CT was better for detecting renal involvement by lymphoma in children, we retrospectively studied 44 patients (6 months to 19 years of age) in whom lymphoma was diagnosed at our hospital during a 5-year period. In no patient was there any clinical evidence of renal disease at the time of presentation. In 39 patients, sonographic and CT findings were similar (normal in 36 patients and showing extrinsic mass effects on the kidneys in three patients). In five patients with non-Hodgkin lymphoma whose contrast-enhanced CT scans showed low-attenuation renal nodules, renal sonography was normal in two, showed renal enlargement in two, and showed a solitary hypoechoic nodule in one patient with multiple, bilateral nodules on CT. Tissue diagnosis of the renal lesions was not obtained, but in the four patients who had follow-up CT, the renal abnormalities resolved after chemotherapy. Our findings suggest that contrast-enhanced CT is superior to sonography for detection of renal lymphoma in children.
为了确定实时超声检查或增强CT在检测儿童淋巴瘤肾脏受累方面哪种方法更好，我们回顾性研究了44例（年龄6个月至19岁）在我院5年期间被诊断为淋巴瘤的患者。在就诊时，没有患者有任何肾脏疾病的临床证据。在39例患者中，超声和CT表现相似（36例正常，3例显示对肾脏的外在肿块效应）。在5例非霍奇金淋巴瘤患者中，增强CT扫描显示肾脏低密度结节，其中2例肾脏超声正常，2例显示肾脏增大，1例在CT上有多个双侧结节的患者显示有一个孤立的低回声结节。未获得肾脏病变的组织学诊断，但在4例接受随访CT检查的患者中，化疗后肾脏异常消失。我们的研究结果表明，增强CT在检测儿童肾脏淋巴瘤方面优于超声检查。
