Different types of anatomical structures can be found in the orbit, such as nerves, muscles, veins, arteries, glandular and connective tissue and hence the differential diagnosis of unilateral proptosis can be vast. In some cases, orbital disease has the potential to cause substantial morbidity and mortality. Appropriate medical history, examination and diagnostic evaluation with imaging can assist with a prompt diagnosis and management. In young infants, a heightened level of suspicion should be maintained since orbital haemangiomas are the most prevalent primary lesions of the orbit presenting with proptosis. We report the case of an infant who presented at 3\u2009months of age to our Emergency Department with a 2-week history of noticeable and progressively worsening right-sided proptosis.<\/jats:p>","DOI":"10.1136\/bcr-2025-266531","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T12:20:15Z","timestamp":1786969215000},"page":"e266531","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Isolated deep orbital haemangioma in an infant presenting to the emergency department with right-sided proptosis"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6437-3736","authenticated-orcid":false,"given":"Eirini Maria","family":"Bikou","sequence":"first","affiliation":[{"name":"Paediatrics, East and North Hertfordshire NHS Trust, Stevenage, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9065-5710","authenticated-orcid":false,"given":"Antonieo Jude Raja","family":"Balraj","sequence":"additional","affiliation":[{"name":"East and North Hertfordshire NHS Trust, Stevenage, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kanimozhi","family":"Tamilselvan","sequence":"additional","affiliation":[{"name":"East and North Hertfordshire NHS Trust, Stevenage, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,8,17]]},"reference":[{"key":"2026081705200524000_19.8.e266531.1","unstructured":"Themes UFO .
