title: Lateral ventricle choroid plexus papilloma in childhood: management and complications.
abstract: BACKGROUND
  A review of the choroid plexus papilloma of the lateral ventricle in the pediatric age group is presented. The characteristic clinical features, imaging studies, preoperative, and operative approaches, as well as complications, will be included.
  
  
  METHODS
  Among a group of 24 patients with ventricular choroid plexus papilloma treated by the authors over a 12-year period, seven patients were selected for this study. The selection included patients under the age of 8 years at the time of their presentation with choroid plexus papilloma of the lateral ventricle. Adult patients and children with choroid plexus papilloma at other sites or choroid plexus carcinoma were excluded. At least a 30-month follow-up period was available for all patients except one. Preoperative and postoperative imaging studies confirming total tumor resection were available for all patients.
  
  
  RESULTS
  Developmental delays and regression were the most consistent clinical features. Magnetic resonance imaging (MRI) proved to be the diagnostic test of choice. The addition of magnetic resonance angiogram (MRA) obviates the need for angiography. Our attempts at tumor embolization failed.
  
  
  CONCLUSIONS
  An intersulcal splitting approach to the lateral ventricular trigone, combined with a perioperative external ventricular drainage, may be of value in the avoidance of symptomatic subdural effusions.
