She presented with severe hypoxaemia, bilateral pulmonary crackles and diffuse opacities on chest imaging without evidence of cardiac dysfunction. Bedside echocardiography and brain natriuretic peptide levels excluded cardiogenic pulmonary oedema. A diagnosis of contrast-induced non-cardiogenic pulmonary oedema was made. She required non-invasive ventilation and supportive therapy with complete resolution over 1\u2009week. This case highlights a rare, life-threatening but reversible reaction to iodinated contrast and underscores the importance of early recognition, prompt respiratory support and readiness with resuscitation equipment during contrast administration.<\/jats:p>","DOI":"10.1136\/bcr-2026-272133","type":"journal-article","created":{"date-parts":[[2026,7,3]],"date-time":"2026-07-03T12:55:58Z","timestamp":1783083358000},"page":"e272133","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Unmasking
