概要

論文の詳細を見る
A 22-year-old woman presented with a very rare extradural en-plaque spinal meningioma manifesting as right hemiparesis and gait disturbance. Magnetic resonance imaging revealed a well-enhanced lesion extending from the C-1 to C-5 vertebral levels, compressing the cord dorsally. Computed tomography revealed a slightly enhanced mass with calcification in the spinal canal, advancing in all directions except anteriorly. Surgery could not completely remove the part of the tumor that had progressed laterally. The histological diagnosis was cervical extradural en-plaque meningioma. Postoperatively, there was remarkable improvement in the patient's symptoms. Successful treatment of this type of tumor requires the development of a combined surgical and radiosurgical approach.
