Typical histopathological findings include eosinophils and Charcot\u2013Leyden crystals within ductal secretions, and characteristic imaging findings include salivary duct dilatation and glandular swelling. Although rare cases associated with sialolithiasis or calcification have been reported, high-attenuation material within the salivary duct on computed tomography (CT) has not been clearly described in ES. Case Presentation: A 56-year-old woman with allergic rhinitis presented with recurrent swelling and pain in the right submandibular area. CT and ultrasonography revealed a large sialolith in the right submandibular gland and dilatation of Wharton\u2019s duct. She underwent right submandibular gland excision for presumed chronic obstructive submandibular sialadenitis with a sialolith. Soon after surgery, she developed recurrent swelling of the right floor of the mouth, and CT showed persistent high-attenuation material along Wharton\u2019s duct without residual sialolith. Ductal massage discharged a brownish gelatinous material. Histopathological examination revealed numerous eosinophils and Charcot\u2013Leyden crystals in both the discharged mucous plug and decalcified sialolith, fulfilling Baer\u2019s diagnostic criteria for ES. Physical extraction and anti-allergic medications were insufficient, whereas ductal irrigation with saline and triamcinolone acetonide markedly reduced mucous plug discharge. Symptoms were controlled during 18 months of follow-up. Conclusions: Retained eosinophilic mucin in ES may appear as high-attenuation ductal material on CT and contribute to salivary stasis and sialolith formation.<\/jats:p>","DOI":"10.3390\/reports9030272","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T08:08:29Z","timestamp":1786694909000},"page":"272","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Case Report of Eosinophilic Sialodochitis with Right Submandibular Sialolithiasis and Hyperattenuating Material Along Wharton\u2019s Duct"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8121-2731","authenticated-orcid":false,"given":"Tomohiro","family":"Kawasumi","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Faculty of Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9728-1264","authenticated-orcid":false,"given":"Takao","family":"Hamamoto","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Faculty of Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0646-0839","authenticated-orcid":false,"given":"Takashi","family":"Ishino","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Faculty of Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9771-3880","authenticated-orcid":false,"given":"Tsutomu","family":"Ueda","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Faculty of Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9853-2501","authenticated-orcid":false,"given":"Sachio","family":"Takeno","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, Faculty of Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"840","DOI":"10.1111\/odi.12595","article-title":"Eosinophilic Sialodochitis: Redefinition of \u201callergic Parotitis\u201d and \u201cSialodochitis Fibrinosa\u201d","volume":"23","author":"Baer","year":"2016","journal-title":"Oral Dis."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Almazrooa, S.
