Key result
Surgical excision of a large anterior mediastinal teratoma achieves symptom-free recovery in a 2-year-old girl.
Why the study?
Mediastinal teratoma presenting with acute respiratory distress and superior vena cava compression is rare.
Case Report (n=1)
Mediastinal tumor should be considered in preschool-age children presenting with nonresolving cough, respiratory difficulty, or SVC syndrome.
Hypothesis-generating for mediastinal teratoma causing acute pediatric SVC syndrome; leaves open optimal diagnostic pathways and management algorithms.
Mediastinal teratoma presenting with acute respiratory distress and superior vena cava (SVC) compression is rare. We report a case of a 2-year-old girl who presented with acute-onset respiratory distress and SVC compression caused by a large anterior mediastinal tumor. Imaging studies revealed a huge mass in the anterior mediastinum extending into the upper right hemithorax. The tumor was surgically excised and histopathologically identified as a mature teratoma. Postoperative recovery was uneventful, and the child remains symptom-free on follow-up. The diagnosis of mediastinal tumor must be considered in any preschool-age child with nonresolving cough, respiratory difficulty, or SVC syndrome.

Siddharth et al. (2026) conducted a case report in Mediastinal teratoma (n=1). Surgical excision was evaluated on Postoperative recovery and symptom status on follow-up. Surgical excision of a large anterior mediastinal mature teratoma in a 2-year-old girl resulted in an uneventful recovery and symptom-free follow-up.
