ENDOSCOPIC ASSISTED, TRANSFONTANELLE EXCISION OF A LARGE THIRD VENTRICULAR ATYPICAL CHOROID PLEXUS PAPILLOMA IN AN INFANT.

Choroid plexus papillomas are rare benign tumours, which are found in both adult and paediatric age groups. The 'atypical' histological subclass is rarer still. The commonest site of occurrence is in the lateral ventricles; rare locations are the cerebellopontine angle and the third ventricle. The goal of care is a gross total excision of the tumour. The histologic subtype determines further adjuvant care given to the patient. The outcome of the care of these patients depends on the histological grade, extent of surgical resection adjuvant care. We present a case of a 12 week-old infant with obstructive hydrocephalus, secondary to a third ventricular atypical choroid plexus papilloma. He had a 'two-staged' resection of the choroid plexus papilloma, using an endoscopic access via the right Kocher's point in the right anterior fontanelle, in the same position as that proposed for access in endoscopic third ventriculostomy because of the observed sutural diastasis. Histology confirmed an atypical choroid plexus papilloma. He made progressive recovery post-surgery but unfortunately there has been default with follow-up clinic visits.
