    Abstract:
    We have recently experienced a dumbbell tumor that developed in the posterior mediastinum in a 64-year-old male. The patient suffered from dorsalgia one year and a half previously. Chest X-ray examinations revealed a well-defined boundary in the right posterior mediastinum. Myelography followed by computerized tomographic scanning (CT) revealed that the tumor developed in a paravertebral area linked with a vertebral canal through an intervertebral foramen and destructed a rib in growing in the paraspinal muscular layer. Longitudinal incision of about 10 cm was made downward from immediately above the first thoracic spinous process, and the chest was opened by posterolateral incision extending into the muscles of the back in an arc shape. The tumor was entirely excised by additional laminectomy. Since malignant schwannoma was diagnosed histologically, Linac X-ray of 50 Gray was given. The patient is now enjoying his healthy daily life with no postoperative complication 2 years after operation. Myelography followed by CT was proved to be quite useful in evaluating a relationship between the tumor and the spinal cord in the diagnosis of this disease.
