This is a slowly progressive and life-threatening disorder and is of paramount importance that this is identified early and treated appropriately. His first chest CT was not typical for IPH, and this appearance should be highlighted (small cystic changes alone initially). He also had focal disease, which allowed us to make the diagnosis using CT-guided biopsy. During his treatment, he experienced an uncommon side effect to a commonly prescribed medication (bradycardia with methylprednisolone). Since starting azathioprine as a steroid-sparing agent, he has been doing well.<\/jats:p>","DOI":"10.1136\/bcr-2024-261171","type":"journal-article","created":{"date-parts":[[2024,6,27]],"date-time":"2024-06-27T22:55:18Z","timestamp":1719528918000},"page":"e261171","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Idiopathic pulmonary haemosiderosis"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8055-7690","authenticated-orcid":false,"given":"Latika","family":"Gupta","sequence":"first","affiliation":[{"name":"Paediatric Respiratory, King's College Hospital NHS Foundation Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Semple","sequence":"additional","affiliation":[{"name":"Paediatric Radiology, Royal Brompton Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon","family":"Padley","sequence":"additional","affiliation":[{"name":"Paediatric Radiology, Royal Brompton Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cara J","family":"Bossley","sequence":"additional","affiliation":[{"name":"Paediatric Respiratory, King's College Hospital NHS Foundation Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,6,27]]},"reference":[{"key":"2025082800504088000_17.6.e261171.1","doi-asserted-by":"crossref","first-page":"3498","DOI":"10.1002\/ppul.26680","article-title":"Subpleural pulmonary cysts in children: associations beyond Trisomy 21","volume":"58","author":"Singh","year":"2023","journal-title":"Pediatr Pulmonol"},{"key":"2025082800504088000_17.6.e261171.2","doi-asserted-by":"publisher","DOI":"10.3109\/15513819109064794"},{"key":"2025082800504088000_17.6.e261171.3","doi-asserted-by":"publisher","DOI":"10.1183\/20734735.0041-2020"},{"key":"2025082800504088000_17.6.e261171.4","doi-asserted-by":"crossref","first-page":"1006","DOI":"10.4103\/jfmpc.jfmpc_2167_22","article-title":"Bradycardia after pulse methylprednisolone therapy in a child-uncommon side effect of a frequently used drug: a case report","volume":"12","author":"Tripathy","year":"2023","journal-title":"J Family Med Prim Care"},{"key":"2025082800504088000_17.6.e261171.5","doi-asserted-by":"crossref","first-page":"106","DOI":"10.1016\/j.jpeds.2017.02.074","article-title":"Bradycardia associated with prednisolone in children with severe Kawasaki disease","volume":"185","author":"Nagakura","year":"2017","journal-title":"J Pediatr"},{"key":"2025082800504088000_17.6.e261171.6","first-page":"171","article-title":"The diagnostic value of CT-guided percutaneous needle lung biopsy in diffuse parenchymal lung diseases","volume":"35","author":"Peng","year":"2012","journal-title":"Zhonghua Jie He He Hu Xi Za Zhi"},{"key":"2025082800504088000_17.6.e261171.7","unstructured":"Talmadge E King RR .
