Abstract A 13-WEEK-OLD male was admitted with a 3-day history of cough and congested breathing. He had no fever, and the parents reported that he was eating well. The results of a physical examination revealed a well-nourished and well-developed infant. He showed respiratory distress, with a respiratory rate of 63/min, and intercostal retractions. The breath sounds were decreased over the right hemithorax. The results of the complete blood cell count and serologic examinations showed no abnormalities. Further evaluation was by chest roentgenography (Figure 1) and computed tomography of the chest (Figure 2). Denouement and Discussion Neonatal Intrathoracic Teratoma Presenting as a Posterolateral Chest Wall Mass A spectrum of germ-cell neoplasms occurs in infancy and childhood in a characteristic midline anatomic distribution.1-9 The sacrococcygeal area is the most common site of teratoma followed in frequency by the ovary. Other sites of origin are the retroperitoneum, mediastinum, head and neck, testis, and References 1. Hedblom CA.
