硬脊膜外转移瘤的治疗不仅困难较多且常提示恶性肿瘤的广泛播散和预后不良。如诊断不及时和治疗不当,便会造成脊髓功能丧失。治疗目的在于保存上肢肌力和括约肌的功能,消除疼痛,从而使患者能相对独立和舒适地生活。发病率:大宗病例表明,转移瘤为椎管内肿瘤最常见类型。多见于50岁以上,占椎管内恶性肿瘤的绝大多数。男性稍多于女性。发生在胸段占50—60%,颈、腰和骶段发病率大致相等。病变通常累及硬脊膜外腔或硬脊膜外腔和椎骨,硬膜内者罕见(2—4%)。从邻近淋巴结直接播散到椎管是众所周知的,但通常是经血流传播。原发于肺癌、乳癌和淋
The treatment of epidural metastases is not only more difficult, but it often suggests widespread dissemination of malignant tumors and poor prognosis. If the diagnosis is not timely and improperly treated, spinal cord function will be lost. The purpose of the treatment is to preserve the muscle strength of the upper extremity and the function of the sphincter and to eliminate the pain so that the patient can live relatively independently and comfortably. Incidence rate: Large cases show that metastatic tumors are the most common type of intraspinal tumor. More common in the age of 50, accounting for the vast majority of malignant tumors in the spinal canal. Men are slightly more than women. Occurred in the thoracic section accounted for 50-60%, the incidence of cervical, lumbar and hernia segments are roughly equal. Lesions often involve the outer dura mater or epidural space and vertebrae, and rare in the dura mater (2-4%). Direct dissemination from adjacent lymph nodes to the spinal canal is well known, but it is usually transmitted through the blood stream. Primarily in lung, breast, and lymphoma
