Childhood choroid plexus neoplasms. A study of 14 cases less than 2 years old

Abstract

Fourteen children less than 2 years old with choroid plexus papilloma (CPP) were studied. Of these patients nine had the tumor in the lateral ventricles (LV), three in the fourth ventricle (4th V), one in the third ventricle (3rd V) and one in the third and left lateral ventricle (LLV). Ten cases showed benign CPP, three cases malignant CPP, and one case had a venous malformation of the choroid plexus (VMCP). Computed tomography (CT) was the best method for neuroradiological study, although a very small CPP in the 3rd V was not detected in an early study. Malignant and benign CPP can be differentiated with CT, especially if the study is performed with contrast media. Pneumoencephalography must be rejected because it is very dangerous and may be the cause of death in some cases. The follow-up of patients with CPP showed a poor prognosis, even after correctly removing the tumor and inserting a shunt.
