A HEALTHY 10-year-old boy had painless, progressive thoracic scoliosis for several years. Computed tomography was performed to evaluate the severity of scoliosis (Figure 1 and Figure 2). The computed tomographic scan was followed by a magnetic resonance imaging study (Figure 3).

Denouement and Discussion  Unusual Radiological Appearance of a Mediastinal Teratoma in ChildhoodThe well-circumscribed appearance and the extensive calcification of the mass are not indicative of a lymphangioma, which infiltrates the mediastinum, and bronchogenic cysts do not calcify. Neuroblastomas calcify, but they originate in the posterior mediastinum and are rarely cystic. The presumptive diagnosis was a teratoma in an unusual location. Resection of the mass went well because of the lack of adhesions and tissue infiltration. A histopathologic examination revealed a mature encapsulated teratoma measuring 9.5×9.5×8 cm; the teratoma had multiple plical structures and contained a thick yellow material. A histological study showed multiple mature tissues.Mediastinal teratomas account
