脊髄神経膠腫

Glioma of Spinal Cord

　一般に髄内腫瘍は稀有なものであるが，最近我我はその3例を経験し，全て神経膠腫であつたので報告し，且つ文献を参省しその病態について少しく考察を加えてみたいと思う。

I have been discussed in detail with pre-sentation of 3cases of the glioma of the spi-nal cords. The clinical features and the cli-nical pathologic studies are described and discussed. The difficulty of differentiating ex-tramedullary tumor from intramedullary one on the basis of the clinical findings alone has been stressed.

According to the experiences cited in the literature, in majority of intrameduallary tumor the history of complaints is usually long, the onset of symptoms is with pain. In others paresthesias appear first. Once these disturbances appear, they are apt to be both persistsnt and progressive. The observation that the lowermost segments are spared or less affected than those at the level of the tumor, may be an important feature. Fibrillation occurred in all our cases in accord with conclusions of many investiga-tor-s. The total protein of spinal fluid may be increased without corresponding pleocy-tosis. Our cases had much difference in the history of complaints, histological studies and prognosis,it depends on the level of the infiltrating tumor, its longitudinal and hori-zontal extent through the spinal cord, the degree of blockage of the subarachnoid spa-ce and the rapidity of growth of tumor.

In additon, our opinions concerned in te-chnique of operation, postoperative treat-ment, classification of histological studies were described.
