He presented with the classic triad of haemoptysis, anaemia and radiological pulmonary infiltrates. Bronchoalveolar lavage sample findings showed features of diffuse alveolar haemorrhage with coexisting features of lipoid pneumonia, with the patient reporting a recent occupational exposure to hydrogenated vegetable oil and kerosene. He was treated with oral corticosteroids and made a rapid and full recovery. This is the first reported case the authors are aware of with such a trigger and these coexisting findings.<\/jats:p>","DOI":"10.1136\/bcr-2024-264643","type":"journal-article","created":{"date-parts":[[2025,6,22]],"date-time":"2025-06-22T20:40:17Z","timestamp":1750624817000},"page":"e264643","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Diffuse alveolar haemorrhage triggered by hydrogenated vegetable oils and kerosene in a patient with a history of idiopathic pulmonary haemosiderosis"],"prefix":"10.1136","volume":"18","author":[{"given":"Bethany","family":"Woodrow","sequence":"first","affiliation":[{"name":"Respiratory Medicine, Lancashire Teaching Hospitals NHS Foundation Trust, Chorley, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yussef","family":"Haider","sequence":"additional","affiliation":[{"name":"Respiratory Medicine, Lancashire Teaching Hospitals NHS Foundation Trust, Chorley, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Nicholson","sequence":"additional","affiliation":[{"name":"Pathology, Lancashire Teaching Hospitals NHS Foundation Trust, Preston, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2025,6,22]]},"reference":[{"key":"2025082702452544000_18.6.e264643.1","doi-asserted-by":"publisher","DOI":"10.1183\/09031936.00119108"},{"key":"2025082702452544000_18.6.e264643.2","doi-asserted-by":"crossref","unstructured":"Fukihara J , Taniguchi H , Ando M , et al .
