视神经胶质瘤

Glioma of optic nerve.with 34 case reports

报告３４例视神经胶质瘤病历，就影像诊断及治疗进行了讨论，并对其中７例有颅内蔓延者进行了随访观察。对２７例眶内视神经胶质瘤病人，２６例行外侧开眶术，１例前路开眶术，全部切除肿瘤。７例颅内蔓延者，５例行外侧开眶术，１例颅眶分次手术，１例因双眼患病而放弃，随访９～１１年眶内肿瘤无复发，颅内肿瘤无进展，对侧眼视功能无继续受损。结果提示，视神经胶质瘤预后较好，颅内蔓延者可先行眶内肿瘤切除，术后随访观察，或结合放射及ｒ－刀等治疗。

Abstract In this paper,34cases of glioma of optic nerve were reported on the imageological diagonosis and the treatment,of which 7 cases with cranial spreading were given following observalion.In 27 cases of orbital glioma the tumors were totally excised by means of lateral orbitotomy in 26 cases and anterior orbitotomy in one case.In other 7 cases with cranial spreading 5 cases performed lateral orbitotomy,one performed craniotomy and orbitotomy successively,and another gave up treatment because the double eyes were involved.9～11 year following observation showed that all the 7 cases had n relapse in their orbitl glioma,no advancement in their craial tumor and no further damage of visual fumction in the other eyes. The results indicate that the glioma of optic nerve have a favorable prognosis.In the case with cranial spreading we can excise orbital tumor first,then give a following observation or other treatment such as radiationtherapy or r knife et al.
