Mediastinum is a common site where benign tumors, like teratomas, can develop. Usually, these lesions do not cause any symptoms and the diagnosis is reached accidentally. As they enlarge they may cause symptoms by compressing the nearby structures of the thorax, mostly the trachea and the bronchi. Extrinsic compression of the heart or the great vessels appears to be a very rare occurrence. Atrial fibrillation as the first clinical presentation of left atrial compression by a giant mediastinal teratoma is extremely uncommon and very few cases have been described in the English literature.
纵隔是良性肿瘤（如畸胎瘤）可能发生的常见部位。通常，这些病变不会引起任何症状，诊断往往是偶然发现的。随着它们的增大，可能会通过压迫胸部附近结构（主要是气管和支气管）而引起症状。心脏或大血管的外部压迫似乎非常罕见。心房颤动作为巨大纵隔畸胎瘤压迫左心房的首发临床表现极为罕见，英文文献中描述的病例很少。
