                                                                A 44-year-old lifelong nonsmoker woman with progressive dyspnoea on exertion, dry cough, and morning neck swelling was referred to our Pulmonary Unit at GB Morgagni Hospital, Forlì, Italy. Initial chest X-ray revealed a significantly enlarged mediastinum with an extensive bilobed opacity. The CT scan of the chest confirmed the presence of an anterior mediastinal mass compressing numerous mediastinal organs. The patient underwent thoracotomy, which allowed for the removal of the mass measuring 23×21×13 cm. The mass was diagnosed as mediastinal mature cystic teratoma.
