뇌실외 배액 후 출혈한 수아세포종 : 증례보고 Report of 2 Cases = Hemorrhage Occurred after External Ventricular Drainage in Medulloblastoma

다국어 초록 (Multilingual Abstract)

The authors experienced 2 cases of medulloblastoma in which active hemorrhage occurred after external ventricular drainage(EVD). A 5 yeardd girl suffered from cerebellar fit and brain CT Scan showed severe hydrocephalus. So EVD was performed and the pressure was measured about 80cm H2O. After a gradual reduction of EVD pressure for 15 minutes, fresh blood gushed out through the EXD catheter. The other case was a 7 year-old girl whose tumor bled after intraoperative EVD, just before dural incision. Both tumors were highly vascular in operative field. The first case was ;)ed-ridden at 5 months after surgery and the second case was on postoperative chemotherapy in a good general condition with minimal neurological deficits. Previous reports in the literatures including 2 cases of hemorrhage associated with EVD in medulloblastoma were reviewed The relatively high incidence of tumor hemorrhage in medulloblastoma and its detrimental influence on the outcome are emphasized
