We reported a dumbbell type tumor of the posterior mediastinum. The patient was an asymptomatic 40-year-old male. An abnormal shadow in the right lower lung field was pointed out in a mass survey. We recognized a dumbbell type tumor in the posterior mediastinum by chest CT and MRI. The tumor invaded the intervertebral canal through the spinal foramen. It was most clearly seen by MRI myelography. Operation was performed with the patient in a prone position and with an L-shaped skin incision of the back and 11th intracostal thoracotomy and Th11 laminectomy. The dumbbell type tumor was completely removed by this operation. The pathological diagnosis was Schwannoma. The post operative course was good. The one-stage operation is useful for dumbbell type tumors of the posterior mediastinum.
我们报告了一例后纵隔哑铃型肿瘤。患者为一名40岁无症状男性。在一次大规模体检中发现右下肺野有异常阴影。通过胸部CT和MRI，我们在后纵隔发现了一个哑铃型肿瘤。肿瘤通过椎间孔侵入椎管。这在MRI脊髓造影中看得最清楚。患者俯卧位，采用背部L形皮肤切口、第11肋间开胸术和第11胸椎椎板切除术进行手术。通过该手术，哑铃型肿瘤被完全切除。病理诊断为神经鞘瘤。术后病程良好。一期手术对后纵隔哑铃型肿瘤是有效的。
