[A case of dumbbell type extradural spinal meningioma].
We reported a case of dumbbell type extradural spinal meningioma. The patient was a 45-year-old female. An abnormal shadow in the right middle 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. Operation was performed firstly with a longitudinal skin incision of the back and Th 6 laminectomy in a prone and secondly with a right posterolateral thoracotomy in a left lateral position. The dumbbell type tumor was completely removed by this operation. The pathological diagnosis was meningioma. The postoperative course was good.
