filum

Conclusion: Ependymomas occur seldom in the conus medullaris and filum terminale but in the upper cord.

结论: 颈胸髓脊髓室管膜瘤的发生率明显高于下部脊髓,圆锥和终丝.

The spinal cords of 193 normal fetal cadavers were observed and measured to obtain the average value of overall length, weight, volume, cervical enlargement, lumbosacral enlargement and the terminal filum of spinal cord before birth.

用193例正常胎儿尸体观察测量了脊髓的全长、重量、体积、颈膨大、腰骶膨大及终丝等方面出生前的逐月发育值及位置的变化。

The lower end of external terminal filum set in position, approximating to the dorsal surface of the1st and2nd coccygeal vertebral bodies.

外终丝止点基本在尾1～尾2椎体间；脊髓长与身长之比逐月下降。

Results: 39 tumors were cervical, 11 were thoracic, and 10 were conus medullaris and filum ferminale.

主要位于胸髓(包括 部分 累及颈髓及腰髓)11例.位于圆锥马尾10例.

MRI examination showed abnormal spinal cord in 11 cases, there were low position spinar cord, coni at lumbus 3 to sacrum 1 with thickened filum terminale in 33 cases.

11例MRI检查显示有脊髓病变，33例MRI检查均显示有低位脊髓、圆锥位于L3～S1和终丝增粗。

Conclusion DTI can well distinguish conus terminalis from filum terminale.

结论脊髓DTI能区分脊髓圆锥与终丝的界限.
