在许多报告脊髓和其鞘膜的肿瘤中,以脑膜瘤最多其发病率为28.5～37.5%。然而,多发性脊髓脑膜瘤却很罕见,Chavany、Rand、Nittner 等曾各报导个别病例,Zervas、Sedzmir 等则报告了颅内和脊髓脑膜瘤同时发生在一个患者身上。本文报告两例多发性脊髓脑膜瘤。例1:64岁,家庭妇女;因下肢痉挛性轻瘫伴深反射亢进和右下肢触觉减退而入院.腹壁反射消失,双侧 Babinski 征阳性,行走困难;无括约肌障碍亦无疼痛。发病4个月,先有右下肢障碍,而后达左下肢。脊髓造影显示在胸_5平面完全阻塞。胸2-5椎板切除术中发现2个硬膜内肿瘤。一个长约3Cm,附着在胸_4左侧神经根并延伸至胸_3;另一个在其下方长1.5Cm,附着在硬膜左内侧壁上。病理检查为沙样脑膜瘤。摘除肿瘤后症状迅速改善。例2:53岁,女性缝纫工人;因双下肢反复疼
In many tumors that report spinal cord and its sheath, the incidence of meningiomas is up to 28.5 to 37.5%. However, multiple spinal meningiomas are rare, with Chavany, Rand, Nittner, and others reporting individual cases. Zervas, Sedzmir et al. reported that both intracranial and spinal meningiomas occur simultaneously in one patient. This article reports two cases of multiple spinal meningiomas. Example 1: 64-year-old, family member; admitted to hospital because of paralysis of lower limb spasticity with hyperreflexia and hypothyroidism in the right lower limb. Abdominal wall reflexes disappeared, bilateral Babinski signs were positive, and walking difficulties; no sphincter disorders and no pain. Four months after onset, there was a right lower limb disorder and then a left lower limb. Myelography showed complete occlusion in the thoracic _5 plane. Two intradural tumors were found during thoracic 2-5 laminectomy. Approximately 3 cm in length, attached to the left nerve root of the thoracic _4 and extending to the thoracic _3; the other is 1.5 cm below it and is attached to the left internal wall of the dura mater. The pathological examination was sand-like meningioma. The symptoms improved rapidly after removal of the tumor. Example 2: 53-year-old female sewing worker; suffers from repeated lower limb pain
