Always expect the unexpected: cystic mediastinal lymphangioma in infants – case report and reviewof the literature

In the paediatric population, mediastinal tumours occur quite often.They include a variety of entities, with different aetiologies.The most common tumours localised in the anterior mediastinum include thymoma, lymphoma, and teratoma.Herein we present the case of an 8-month-old female infant diagnosed with a huge mediastinal solid-cystic tumour causing superior vena cava syndrome.Ultrasonography-guided needle aspiration was performed.The aspirated fluid contained no epithelial cells but many lymphocytes and neutrophils, based on a cytological analysis.The culture of the material revealed Staphylococcus aureus MRSA.In accordance with the antibiogram, the vancomycin therapy was continued.The antibiotic treatment was continued for 6 weeks achieving complete remission of the lymphangioma, which had lasted for one year.
