... [1] Hydrocephalus is a state in which abnormal dilation of the ventricle occurs due to a circulatory or absorptive disorder of the CSF. [2] A relationship between hydrocephalus and meningitis has been proposed, [3,4] with Uehara et al. suggesting that bacteria causing meningitis may cause exudative inflammation and infiltration of many neutrophils in the arachnoid space in 2 months after resection of a cervical cord tumor. [3] Kumaki et al. reported that a fibrinous component also develops, which spreads to the brain surface or subarachnoid space and causes adhesion, which impairs CSF circulation and finally leads to hydrocephalus in 5 months after cervical laminoplasty. ...

... Accordingly, the postoperative behavior of remnant tumors after IR, rather than the recurrence rate of tumors after GTR, should be highlighted, and several studies have investigated it. 4,7,[12][13][14][15] However, the reported growth rates of remnant tumors ranged widely from 16.7% 15 to 60%, 12,13 and most studies have failed to propose clinical implications to predict remnant tumor growth. Thus, this study investigated remnant tumor growth after IR of cervical DS and identified its predictive factors. ...
