Superior vena cava syndrome in children

Superior vena cava syndrome (SVCS) is rare in childhood. 18 cases of SVCS were seen in children ranging from 3-14 years with a mean age of 8.8 years. There were 15 males and 3 female children. Diagnosis could be confirmed in 17 cases as one child succumbed to severe respiratory distress without a definitive diagnosis. The commonest cause of SVCS was lymphoma. Non-Hodgkin's lymphoma (NHL) was more common than Hodgkin's disease. In two cases the final diagnosis was tuberculosis of mediastinal lymph nodes. The diagnosis was confirmed by cervical lymph node biopsy in 6 cases, mediastinal biopsy in 6 cases and bone marrow aspiration in the remaining 5 cases. Intravenous Dexamethasone provided relief of symptoms in 13 patients. None of the children received emergency radiotherapy. Anti-tubercular treatment produced complete cure in the two patients with tubercular mediastinal lymphadenopathy. © Indian Society of Haematology & Transfusion Medicine 2008.
