제 3 및 제 4뇌실에 발생한 맥락총 유두종

Abstract

Choroid plexus papilloma(CPP) is a rare intraventricular neoplasm occurring primarily in the lateral ventricle of children and the 4th ventricle of adults. The 3rd ventricle is an extremely rare site for CPP to occur. The authors report two cases of CPP of the 3rd ventricle in a 2-month-old girl and a 4-month-old boy, and one case of CPP of the 4th ventricle in a 17-year-old male. Two CPP of third ventricle were totally removed by transcortical-transventricular approach and transcallosal subchoroidal approach, respentively. The CPP in the fourth ventricle was totally removed by suboccipital approach. The subdural hygroma and hydrocephalus due to CSF overproduction was managed with subduroperitoneal shunt and ventriculoperitoneal shunt.
