Background: Mediastinal teratomas are rare. Nevertheless, they represent the most frequent mediastinal germ cell tumours. The aim of our work is to study the anatomoclinic and radiological features of these mediastinal tumours.Methods: This is a retrospective study carried out in the CHU Hassan II department of thoracic surgery between June 2009 and May 2017, collecting 8 teratomas from the mediastinum.Results: They are 5 women and 3 men with an average age of 37 years (extremes of 16 to 65 years). The main sign revealing was chest pain in three cases. We noticed a complex rupture in the bronchi and the lung in one case, associated with a cutaneous fistula in another patient. The radiological assessment showed an evocative aspect of a mediastinal teratoma with ranges of variable densities: solid, fluid, fat and calcium only in three patients. The surgical exploration by posterolateral thoracotomy had allowed the complete resection of the tumor in the cases. Anatomopathological examination of the room confirmed the diagnosis of a mature teratoma in all patients.Conclusion: The clinical picture of mediastinal mature teratomas is non-specific. The association with a rupture testifies to the long evolution of this disease. The imaging is often atypical showing entirely cystic lesions.
