The purpose of this paper was to illustrate the imaging features of this lesion to avoid unnecessary investigations.<\/jats:p><\/jats:sec>Methods<\/jats:title>The clinical notes and imaging features of four patients with a diagnosis of sternal pseudotumour were reviewed over a period from February 2016 to July 2019.<\/jats:p><\/jats:sec>Results<\/jats:title>All patients were afebrile with no history of trauma. The median age at presentation was 12.5\u2009months. The median length of symptoms prior to presentation was 3.5\u2009days. One patient had a mildly elevated C\u2010reactive protein. Chest radiographs showed a pre\u2010sternal soft\u2010tissue mass, with or without osseous destruction of the subjacent sternum. Ultrasound showed a heterogeneous, hypoechoic pre\u2010sternal soft\u2010tissue mass with variable internal vascularity with extension between sternal ossification centres. CT and MRI showed an enhancing dumbbell\u2010shaped lesion with a pre\u2010sternal and retro\u2010sternal soft\u2010tissue component. The median time to complete resolution was 3\u2009months. One patient had a biopsy that showed chronic inflammation and fibrosis.<\/jats:p><\/jats:sec>Discussion<\/jats:title>These lesions present in young children typically with a 1\u2010 to 2\u2010week history of a focal 2\u2010 to 4\u2010cm swelling over the sternum. The aetiology is unknown but may be on the basis of a yet\u2010to\u2010be identified pathogen. Inflammatory markers and cultures are normal or mildly elevated. Important differential considerations include sternal osteomyelitis or neoplastic causes such as Ewing sarcoma, rhabdomyosarcoma, Langerhans cell histiocytosis and infantile fibrosarcoma.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>Sternal pseudotumor is a rare but important entity to be aware of to avoid unnecessary invasive biopsy or further investigations. Our suggestion is that this is a \u2018Don't touch\u2019 lesion that requires close short\u2010interval follow\u2010up at a surgical outpatient clinic and with ultrasound until resolution.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajum.12376","type":"journal-article","created":{"date-parts":[[2024,2,7]],"date-time":"2024-02-07T08:50:20Z","timestamp":1707295820000},"page":"124-130","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Sonographic features of sternal pseudotumour in children"],"prefix":"10.1002","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0353-2788","authenticated-orcid":false,"given":"Samantha","family":"Gerrie","sequence":"first","affiliation":[{"name":"Radiology Starship Children's Hospital Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mike","family":"Watson","sequence":"additional","affiliation":[{"name":"LabPLUS Auckland City Hospital Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phil","family":"Morreau","sequence":"additional","affiliation":[{"name":"Paediatric Surgery Starship Children's Hospital Auckland New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,2,6]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/1096-911X(200008)35:2<135::AID-MPO11>3.0.CO;2-W"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.7863\/ultra.32.12.2199"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/652539"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.105.1.29"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/pbc.22454"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-020-04827-6"},{"issue":"4","key":"e_1_2_8_8_1","first-page":"1","article-title":"Subacute sternal mass in childhood","volume":"103","author":"Verhaeghe L","year":"2019","journal-title":"J Belg Soc Radiol"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rx.2018.07.006"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2015.05.133"}],"container-title":["Australasian Journal of Ultrasound in Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajum.12376","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,6,3]],"date-time":"2024-06-03T10:02:02Z","timestamp":1717408922000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajum.12376"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,2,6]]},"references-count":9,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2024,5]]}},"alternative-id":["10.1002\/ajum.12376"],"URL":"https:\/\/doi.org\/10.1002\/ajum.12376","archive":["Portico"],"relation":{},"ISSN":["1836-6864","2205-0140"],"issn-type":[{"value":"1836-6864","type":"print"},{"value":"2205-0140","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,2,6]]},"assertion":[{"value":"2024-02-06","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
