Because these lesions may appear as small hepatic or perihepatic nodules, they can mimic primary or metastatic hepatic tumors on screening imaging. Here, we report the case of a 55-year-old asymptomatic man with no relevant medical history who was referred after routine health-screening ultrasonography revealed a 10\u2009\u00d7\u20098-mm hyperechoic lesion adjacent to the surface of liver segment VI. Liver function tests were normal, hepatitis B and C viral markers were negative, and tumor markers, including carcinoembryonic antigen, carbohydrate antigen 19-9, alpha-fetoprotein, and protein induced by vitamin K absence or antagonist-II, were within the normal ranges. Dynamic ultrasonography demonstrated that the lesion was located along the hepatic capsule, rather than within the deep hepatic parenchyma. Computed tomography showed a well-demarcated hepatic surface lesion with central calcification and surrounding fat attenuation, without any arterial, portal venous, or delayed enhancement. Gadoxetate disodium-enhanced magnetic resonance imaging revealed fat-containing signal characteristics, no hepatobiliary-phase uptake, and no diffusion restriction. The integrated multimodal imaging findings supported a diagnosis of presumed hepatic pseudolipoma, likely originating from a detached epiploic appendage. Recognition of this benign hepatic tumor mimic may help to avoid unnecessary biopsy or surgery.<\/jats:p>","DOI":"10.1093\/bjrcr\/uaag040","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T13:25:26Z","timestamp":1790861126000},"source":"Crossref","is-referenced-by-count":0,"title":["Presumed hepatic pseudolipoma detected as a small hepatic surface lesion: multimodality imaging findings"],"prefix":"10.1093","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2916-2268","authenticated-orcid":false,"given":"Koichi","family":"Soga","sequence":"first","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University Saitama Medical Center , Koshigaya, Saitama 343-8555,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ou","family":"Takagi","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University Saitama Medical Center , Koshigaya, Saitama 343-8555,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kohei","family":"Inaba","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University Saitama Medical Center , Koshigaya, Saitama 343-8555,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikako","family":"Masuda","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University Saitama Medical Center , Koshigaya, Saitama 343-8555,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ikuhiro","family":"Kobori","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University Saitama Medical Center , Koshigaya, Saitama 343-8555,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsutoshi","family":"Sugimoto","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Dokkyo Medical University Saitama Medical Center , Koshigaya, Saitama 343-8555,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,10,1]]},"reference":[{"key":"2026101108411608700_uaag040-B1","doi-asserted-by":"publisher","first-page":"83","DOI":"10.3109\/00313028309061407","article-title":"Hepatic pseudolipoma","volume":"15","author":"Pounder","year":"1983","journal-title":"Pathology"},{"key":"2026101108411608700_uaag040-B2","doi-asserted-by":"publisher","first-page":"877","DOI":"10.1136\/jcp.38.8.877","article-title":"Hepatic pseudolipoma","volume":"38","author":"Karhunen","year":"1985","journal-title":"J Clin Pathol."},{"key":"2026101108411608700_uaag040-B3","doi-asserted-by":"publisher","first-page":"345","DOI":"10.1136\/jcp.39.3.345","article-title":"Pseudolipoma of Glisson\u2019s capsule simulating metastatic tumour","volume":"39","author":"Benbow","year":"1986","journal-title":"J Clin Pathol."},{"key":"2026101108411608700_uaag040-B4","doi-asserted-by":"crossref","first-page":"75","DOI":"10.1097\/00004836-199407000-00018","article-title":"Pseudolipoma of Glisson\u2019s capsule.
