It occurs more frequently in the digestive tract, but has also been reported outside the gastrointestinal tract. This report details a case of rare hepatic anisakiasis that was initially diagnosed as metastatic rectal cancer.<\/jats:p>\n <\/jats:sec>\n \n Presentation of case<\/jats:title>\n A 60-year-old male underwent radical resection for stage III rectal cancer followed by adjuvant chemotherapy for six months. Seven months after surgery, a new, 10 mm diameter area of low density was seen in segment 4\/8 margin of the liver on enhanced computed tomography (CT) scan. Metastatic liver tumour from rectal cancer was suspected. Laparoscopic partial hepatectomy was performed. The diagnosis was revised to hepatic anisakiasis when pathological examination revealed anisakis simplex larvae in the necrotic tissue.<\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n Anisakiasis outside of the gastrointestinal tract is a rare finding, but may be seen more frequently with the recent increase in the consumption of raw fish around the world. Hepatic anisakiasis may mimic tumours in the liver. Clinicians should consider dietary inquiry and further evaluation in patients with liver margin tumours less than 20 mm in size that are not positively malignant, as hepatic anisakiasis may be a possible diagnosis.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n We report a rare case of hepatic anisakiasis which initially presented as suspected metastatic cancer. Hepatic anisakiasis should be considered in the differential diagnosis of low density liver tumours less than 20 mm, where the patient\u2019s diet includes raw fish.<\/jats:p>\n <\/jats:sec>\n \n Highlights<\/jats:title>\n <\/jats:sec>","DOI":"10.1016\/j.ijscr.2019.06.010","type":"journal-article","created":{"date-parts":[[2019,6,12]],"date-time":"2019-06-12T02:52:54Z","timestamp":1560307974000},"page":"209-212","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":14,"title":["Hepatic anisakiasis mimicking metastatic liver tumour"],"prefix":"10.1097","volume":"60","author":[{"given":"Ryosuke","family":"Kita","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroki","family":"Hashida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Uryuhara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Kaihara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-53-20260114","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1016\/0304-4017(88)90148-3","article-title":"Standardized nomenclature of animal parasitic diseases (SNOAPAD)","volume":"29","author":"Kassai","year":"1988","journal-title":"Vet.
