When the lesion is located in the mediastinum, the diagnosis of CD is easy. However, if the lesion presents as a perigastric mass mimicking other subserosal gastric mesenchymal tumors, the diagnosis can be challenging. As few sonographic manifestations of hyaline-vascular variant CD, especially contrast-enhanced ultrasound (CEUS) imaging, as well as computed tomography (CT) and histopathological imaging, have been reported in literature, this case may provide a vivid example of a comprehensive CEUS and CT usage in the diagnosis and surgery with regard to CD. This report presents a case of a 50-year-old female diagnosed with hyaline-vascular variant CD in a random physical examination, the ultrasound examination first revealed a 24.3 mm \u00d7 15.4 mm hypoechogenic lesion abutting the stomach, esophagus, and liver, which was under the suspicion of gastrointestinal stromal tumor. Following a series of medical examinations, including CEUS, CT, postoperative histopathological examination, and immunohistochemical analysis, the patient was diagnosed with hyaline-vascular variant unicentric CD. After the mass was completely excised through laparoscopic surgery, the woman recovered very well without recurrence during a follow-up period of 15 months. Thus, mastering ultrasound and CT-imaging characteristics of CD and applying ultrasound and CT examination together would do help to preoperative diagnosis. <\/jats:p>","DOI":"10.1159\/000513175","type":"journal-article","created":{"date-parts":[[2021,7,9]],"date-time":"2021-07-09T21:01:06Z","timestamp":1625864466000},"page":"632-638","source":"Crossref","is-referenced-by-count":1,"title":["Perigastric Hyaline-Vascular Variant Castleman\u2019s Disease"],"prefix":"10.1159","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2102-1439","authenticated-orcid":false,"given":"Yu Ming","family":"Jin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gui Ying","family":"Jing","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2021,7,9]]},"container-title":["Case Reports in Gastroenterology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/513175","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/513175","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:11:31Z","timestamp":1745424691000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000513175"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,7,9]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2021,9,2]]}},"URL":"https:\/\/doi.org\/10.1159\/000513175","archive":["Portico"],"relation":{},"ISSN":["1662-0631"],"issn-type":[{"type":"electronic","value":"1662-0631"}],"subject":[],"published":{"date-parts":[[2021,7,9]]}}}
