神经鞘膜肿瘤有神经鞘瘤(neurilemmoma)和神经纤维瘤(neurofibroma)两类;两者均为神经鞘细胞来源,小肿瘤可无症状,较大者因受累神经受压而引起麻痹或疼痛,并沿神经放射。大多数肿瘤能手术根治,极少数与脊髓等紧密粘连未能完全切除者可复发。以上两型肿瘤均可发生恶变,但较多见于神经纤维瘤,神经鞘瘤复发可能性低,即使复发肿瘤大多仍属良性;本科室于2012年7月收治一例经病理证实位于S1-3椎管内及骶椎骨质内的巨大神经鞘瘤,采用后正中稍向左侧孤形入路手术完全切除,术后2个月复查MRI未见复发。
Nerve sheath tumors have neurilemmoma and neurofibroma. Both are sources of nerve sheath cells. Small tumors may be asymptomatic. Larger tumors may cause numbness or pain due to compression of the involved nerves. And along the nerve radiation. Most tumors can be radical surgery, a very small number of closely linked with the spinal cord and other patients can not be completely resected recurrence. More than two types of tumors can occur malignant, but more common in neurofibromatosis, schwannoma recurrence is low, even if the recurrence of the tumor is still mostly benign; undergraduate in July 2012 admitted to a case confirmed by pathology in the S1-3 vertebra Intranasal and sacral vertebra within the huge schwannoma, using the middle of the left slightly isolated solitary approach surgery completely removed, 2 months after the review of MRI did not recur.
