Abstract：
Anisakiasis is a parasitic infection caused by the ingestion of raw or undercooked seafood infected with Anisakis larvae. It generally affects the gastrointestinal tract, particularly the stomach, but very rare cases have been reported in which infection of the liver leads to the formation of inflammatory pseudotumors. We herein report an extremely rare case of an inflammatory pseudotumor induced by hepatic anisakiasis that was laparoscopically resected for the purpose of both diagnosis and treatment. A 51-year-old woman underwent a routine medical checkup by ultrasound examination, which incidentally detected a 15-mm mass on the surface of S6 of the liver. Because a malignant tumor could not be ruled out on several preoperative imaging studies, laparoscopic partial resection of the liver was performed. Histopathological examination revealed Anisakis larva in the inflammatory pseudotumor, suggesting hepatic anisakiasis. This report describes an extremely rare case of an inflammatory pseudotumor induced by hepatic anisakiasis. Because the preoperative diagnosis could not be obtained by several imaging modalities, laparoscopic liver resection with a sufficient margin might be suitable for diagnosis and treatment of this disease.
摘要：
异株病是由摄入感染异株幼虫的生的或未煮熟的海鲜引起的寄生虫感染。它通常会影响胃肠道，尤其是胃，但是据报道，肝脏感染导致炎性假瘤形成的病例非常罕见。我们在此报告了一例极为罕见的由肝anisakiasis引起的炎性假瘤，该病例经腹腔镜切除以进行诊断和治疗。一名51岁的妇女接受了超声检查的常规体检，偶然发现肝脏S6表面有一个15毫米的肿块。因为在一些术前影像学研究中不能排除恶性肿瘤，行腹腔镜肝脏部分切除术。组织病理学检查显示炎性假瘤中的异尖幼虫，提示肝茴香病.本报告描述了由肝anisakiasis引起的炎性假瘤的极为罕见的病例。因为术前诊断不能通过几种成像方式获得，具有足够切缘的腹腔镜肝切除术可能适合诊断和治疗该疾病。
