Methods
Eight children (below 12 years of age) operated on for intraventricular choroid plexus papilloma (CPP) were retrospectively reviewed to identify the factors responsible for their high postoperative morbidity and mortality. Seven of these patients were aged between 2 months and 2 years and 1 was aged 12 years. Six CPP lesions were in the lateral ventricles and the remaining 2 were in the anterior third ventricle. All children presented with features of raised intracranial pressure. Due to gross hydrocephalus with severe manifestations at admission two patients required CSF diversion before definitive surgery.
Results
Microsurgical excision of CPPs was achieved in 7 and near total removal of the tumor in an 8th child. Brain shift was noted during operation and was attributed to acute CSF drainage and/or tumor excision in all cases. External ventricular drainage was postoperatively placed in 2 patients, who ultimately required shunt installation. One child died during definitive surgery. Due to neurological deterioration 6 of the remaining 7 patients had a postoperative CT scan within a week of surgery. One had an uneventful recovery, and pneumocephalus and subdural effusion were found in all 6 scanned children. Pneumocephalus was significant enough in 4 of them to warrant a surgical evacuation.
Conclusion
Acute CSF drainage leading to significant intraoperative brain shift, postoperative external ventricular drainage, pneumocephalus, subdural effusion, and persistent postoperative hydrocephalus were identified as chief factors for higher morbidity in these children.
