Her medical history was notable for chronic myeloid leukaemia, for which she took imatinib. Due to a possible association between imatinib and GAVE described in a small number of case reports, cessation of imatinib was trialled. This led to a significant improvement in the patient\u2019s anaemia and resolution of GAVE on repeat endoscopy. GAVE is an uncommon cause of gastrointestinal bleeding, the aetiology of which is uncertain. This report describes an approach to the differential diagnosis of chronic iron-deficiency anaemia and an overview of GAVE syndrome. It illustrates the benefit of broadening the differential when the diagnosis is uncertain and the utility of case reports in informing the differential diagnosis.<\/jats:p>","DOI":"10.1136\/bcr-2023-257620","type":"journal-article","created":{"date-parts":[[2024,2,22]],"date-time":"2024-02-22T12:35:26Z","timestamp":1708605326000},"page":"e257620","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Resolution of gastric antral vascular ectasia following cessation of imatinib"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8116-1444","authenticated-orcid":false,"given":"James A","family":"Maye","sequence":"first","affiliation":[{"name":"Medicine, West Suffolk Hospital, Bury Saint Edmunds, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0038-2657","authenticated-orcid":false,"given":"Olivia","family":"Baker","sequence":"additional","affiliation":[{"name":"Medicine, West Suffolk Hospital, Bury Saint Edmunds, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadim","family":"Sheikh","sequence":"additional","affiliation":[{"name":"Gastroenterology, West Suffolk Hospital, Bury Saint Edmunds, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2024,2,22]]},"reference":[{"key":"2025082802085668000_17.2.e257620.1","doi-asserted-by":"crossref","first-page":"46","DOI":"10.7812\/TPP\/09-055","article-title":"Gastric antral vascular ectasia (watermelon stomach)\u2014an enigmatic and often-overlooked cause of gastrointestinal bleeding in the elderly","volume":"13","author":"Nguyen","year":"2009","journal-title":"Perm J"},{"key":"2025082802085668000_17.2.e257620.2","doi-asserted-by":"crossref","unstructured":"Peng M , Guo X , Yi F , et al .
