Abstract：
We report a case of reactive lymphoid hyperplasia (RLH) mimicking colorectal liver metastases (CRLM) on preoperative workup that was clinically indistinguishable. A 78-year-old woman was found to have locally-advanced sigmoid cancer (T4), and then treated with radical sigmoidectomy. One year after the surgery, plain computed tomography (CT) revealed a low-density area in the right hepatic lobe. Metastatic liver tumors could not be ruled out with CT/ magnetic resonant imaging (MRI) and positron emission tomography-CT . Based on these findings, the patient was diagnosed with CRLM at S7 of the liver. The patient underwent right posterior sectionectomy. The tumor was adjacent to the right hepatic vein; however, no invasion was observed. The patient was pathologically diagnosed as having RLH. The patient showed no signs of recurrence 16 months after initial surgery. RLH is clinically indistinguishable from CRLM. Further evaluation is required to elucidate the effective strategies of detecting and treating hepatic RLH.
摘要：
我们报告了一例反应性淋巴增生（RLH），在术前检查中模仿结直肠癌肝转移（CRLM），临床上无法区分。一名78岁的妇女被发现患有局部晚期乙状结肠癌（T4），然后用根治性乙状结肠切除术治疗.手术一年后,普通计算机断层扫描（CT）显示右肝叶有一个低密度区域。CT/磁共振成像（MRI）和正电子发射断层扫描-CT不能排除转移性肝肿瘤。基于这些发现,患者在肝脏S7被诊断为CRLM.患者接受了右后段切除术。肿瘤与右肝静脉相邻；然而，没有观察到入侵。患者经病理诊断为患有RLH。患者在初次手术后16个月没有复发的迹象。RLH在临床上与CRLM没有区别。需要进一步评估以阐明检测和治疗肝RLH的有效策略。
