GIANT LEFT THORACIC TERATOMA IN INFANCY: A SURGICAL CASE REPORT

Abstract

Introduction: Mature intrathoracic teratomas are rare benign germ cell tumors, particularly in infancy. Most commonly arising in the anterior mediastinum, these tumors may be asymptomatic or present with symptoms due to compression of thoracic structures. Case Presentation: We report a case of a five-month-old male presenting with respiratory distress and failure to thrive. Imaging revealed a large heterogeneous mass occupying the left hemithorax. Tumor markers were within age-appropriate limits. A posterolateral thoracotomy was performed, and the mass was excised piecemeal. Postoperative recovery was uneventful, and follow-up at six months confirmed no recurrence. Conclusion: Although rare in infants, intrathoracic teratomas should be considered in the differential diagnosis of respiratory compromise. Early diagnosis through imaging and prompt surgical intervention can lead to excellent outcomes. This case highlights the clinical, radiologic, and surgical considerations in managing mediastinal teratomas in very young children.
