Presentation
Increasing head circumference.
Patient Data
Transcranial ultrasound demonstrates hydrocephalus and a large intraventricular mass located in the trigone of the lateral ventricle on the left.
The child went on to have a ventriculoperitoneal shunt inserted.
CT obtained following insertion of a right sided VP shunt demonstrates a large vividly enhancing intraventricular mass, located at the trigone of the lateral ventricle on the left.
A biopsy was carried out and the child was imaged again a couple of months later.
MRI obtained only 2 month later demonstrates the mass to have markedly increased in size with intraventricular and leptomeningeal spread. The 4th ventricle is now trapped and ballooned.
Case Discussion
Features are consistent with a choroid plexus carcinoma, even though the initial appearance would have also been consistent with a choroid plexus papilloma. The diagnosis was confirmed histologically. The child passed away shortly after the last scan.
