原发性颅内脑膜瘤历来很少转移至颅外。作者最近遇见两例病理证实的远处转移,第一例是原发于右顶枕叶的矢状面脑膜瘤,先后于1965年和1971年两次开颅切除肿瘤(第一次为次全切除,第二次是将复发的肿瘤肉眼下全部切除),第二次手术后15个月因病人出现背痛而发现胸、腰段硬脊膜外(胸段伴有两个椎弓根的骨质破坏)和右后第七肋骨的脑膜瘤转移,经放射治疗后疼痛显著减轻。第二例是原发于左大脑半球凸面的脑膜瘤,先后于1957年和1970年两次开颅
Primary intracranial meningioma has rarely been transferred to the extracranial. The authors recently met with two pathologically confirmed distant metastases, the first being the sagittal meningioma of the primary origin in the occipital lobe of the right upper quadrant, followed by two craniotomy resections in 1965 and 1971 (first subtotal Resection, the second is the total resection of the tumor resection of the tumor), 15 months after the second operation due to patient back pain and found the thoracic, lumbar epidural (thoracic with two pedicles Bone destruction) and meningioma metastasis of the seventh right rib, the pain was significantly reduced after radiotherapy. The second case is the meningioma of the primary origin in the convex surface of the left hemisphere, which was craniotomized two times in 1957 and 1970
