We report the case of a 58\u2010year\u2010old man with a history of autoimmune pancreatitis (AIP) who presented with incidentally detected multiple hepatic lesions. Serum IgG4 was markedly elevated to 7546.6\u2009mg\/L. Contrast\u2010enhanced ultrasound (CEUS) suggested cholangiocarcinoma, contrast\u2010enhanced computed tomography (CECT) and magnetic resonance imaging (CEMR) favored hepatic abscesses, while\n                    <jats:sup>18<\/jats:sup>\n                    F\u2010FDG PET\u2010CT supported an inflammatory process. As the patient declined biopsy, a clinical diagnosis was made based on prior IgG4\u2010RD, serological findings, and multimodal imaging features, and empirical immunosuppressive therapy was initiated. Subsequent follow\u2010up demonstrated significant lesion regression. Although histopathological confirmation was unavailable, the constellation of clinical, serological, and imaging findings was consistent with a presumptive diagnosis of IgG4\u2010related hepatic inflammatory pseudotumor. This case offers important insights into the imaging differentiation and noninvasive management of IgG4\u2010HIPT.\n                  <\/jats:p>","DOI":"10.1002\/jcu.70158","type":"journal-article","created":{"date-parts":[[2025,12,5]],"date-time":"2025-12-05T03:41:17Z","timestamp":1764906077000},"page":"1253-1257","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Diagnostic and Follow\u2010Up Value of Contrast\u2010Enhanced Ultrasound of\n                    <scp>IgG4<\/scp>\n                    \u2010Associated Hepatic Inflammatory Pseudotumor: A Case Report and Review"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-8589-982X","authenticated-orcid":false,"given":"Feile","family":"Ye","sequence":"first","affiliation":[{"name":"Department of Ultrasound Medicine The Fifth Affiliated Hospital of Sun Yat\u2010sen University  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7281-7357","authenticated-orcid":false,"given":"Zhongzhen","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Ultrasound Medicine The Fifth Affiliated Hospital of Sun Yat\u2010sen University  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6080-0183","authenticated-orcid":false,"given":"Ting","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Ultrasound Medicine The Fifth Affiliated Hospital of Sun Yat\u2010sen University  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,12,4]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijms26115325"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jum.16629"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.5114\/pjr.2020.95781"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10396\u2010015\u20100624\u20106"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12328\u2010021\u201001526\u2010z"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.11152\/mu\u20102542"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.3389\/fonc.2021.737099"},{"key":"e_1_2_10_9_1","first-page":"255","article-title":"Simultaneous Non\u2010Functioning Neuroendocrine Carcinoma of the Pancreas and Extra\u2010Hepatic Cholangiocarcinoma.
