It often lacks specific clinical and imaging features, leading to misdiagnosis.We present a case of IgG4-RSGI to enhance clinical recognition and diagnostic accuracy. A patient presented with a four-month history of progressive bilateral submandibular gland enlargement. Ultrasonography revealed bilateral submandibular gland enlargement with heterogeneous internal echoes, a \"mesh-like\" pattern, and nodular hypoechoic areas. Color Doppler flow imaging (CDFI) showed increased vascularity. Ultrasound-guided biopsy confirmed the diagnosis, establishing ultrasound as a valuable initial diagnostic tool in the clinical assessment of IgG4-RSGI.<\/jats:p>","DOI":"10.1007\/s40477-025-01087-8","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T17:01:43Z","timestamp":1759165303000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ultrasonographic features and clinical management of IgG4-related submandibular gland inflammation: a case report"],"prefix":"10.1007","author":[{"given":"Wenhui","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nan","family":"Pang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xu","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Fang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youjun","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruixue","family":"Lu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,9,29]]},"reference":[{"issue":"1","key":"1087_CR1","doi-asserted-by":"publisher","first-page":"186","DOI":"10.1186\/s13075-015-0698-y","volume":"17","author":"W Li","year":"2015","unstructured":"Li W et al (2015) Clinicopathological characteristics of immunoglobulin G4-related sialadenitis.
