An Unusual Presentation of Life-Threatening Necrotising Mediastinitis in an Adolescent.

A male in early adolescence presented with 1 week of chest pain, respiratory symptoms and diarrhoea. Thoracic computed tomography (CT) revealed suspicious findings of necrotising mediastinitis without signs of a descending infection. The patient underwent bilateral thoracotomy and laparotomy with several revisions. After 58 days in the hospital, the patient was discharged home, fully recovered, with no sequelae. This case highlights the importance of a multidisciplinary approach when managing severe and rare conditions, emphasising the need for early diagnosis and prompt, appropriate surgical treatment.
