A 44-year-old male presented with right chest pain after falling from a height of 2 m. In this study, a rare, mature cystic teratoma that was associated with an anterior intrathoracic meningocele and that developed in the posterior mediastinum is presented. To the best of our knowledge, in Turkey, there has been no case of a posterior mediastinal teratoma associated with an anterior intrathoracic meningocele in the medical literature.
