| ABSTRACT |
|
The authors experienced 2 cases of medulloblastoma in which active hemorrhage occurred after external ventricular drainage(EVD). A 5 year-old girl suffered from cerebellar fit and brain CT scan showed severe hydrocephalus. So EVD was performed and the pressure was measured about 80 cm H2O.
After a gradual reduction of EVD pressure for 15 minutes, fresh blood gushed out through the EVD 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 bed-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. |
