The patient had a prior history of Ewing sarcoma of the pelvis in young age, which had been treated with chemoradiotherapy with remission. There was a 2\u2010week history of right sided chest pain and shortness of breath, and a chest x\u2010ray showed complete opacification of the right hemithorax, with subsequent CT arising suspicion of a heterogeneous soft tissue pleural lesion with fluid in the pleural cavity. While awaiting further treatment including biopsy, the patient deteriorated rapidly and was eventually started on end\u2010of\u2010life care. Postmortem examination showed large right pleural haemorrhage with lung collapse, and histological examination of pleural lesions confirmed a diagnosis of recurrent Ewing\u2032s sarcoma. Extraskeletal presentations of Ewing\u2032s sarcoma, particularly with spontaneous haemothorax as the initial presentation have been rarely reported in the literature in adult patients. Diagnosing pleural Ewing\u2032s sarcoma requires a multimodal approach, utilising investigations such as contrast\u2010enhanced CT imaging, pleural fluid analysis, thoracoscopy, and PET\u2010CT to evaluate for disease spread. Treating pleural Ewing\u2032s sarcoma can be challenging; early diagnosis and management of complications such as haemothorax is essential with thoracocentesis or thoracotomy. Ongoing treatment can include multimodal therapies including chemotherapy and radiotherapy with or without surgery, depending on disease extent.<\/jats:p>","DOI":"10.1155\/crpu\/2865406","type":"journal-article","created":{"date-parts":[[2026,5,20]],"date-time":"2026-05-20T10:12:08Z","timestamp":1779271928000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spontaneous
