Choroid plexus carcinomas occur within the ventricles of the brain and can block the cerebro-spinal fluid from circulating and draining, causing pressure to build up in the skull.
Choroid plexus carcinoma's occur most often in one year olds, where the signs of the raised intracranial pressure may be vomiting and lethargy (drowsiness) or your child being unable to look upwards. Their head size may also grow quickly.
Choroid plexus carcinomas are a high grade (grade 3), fast growing tumour. There is an association with the genetic condition, Li-Fraumeni syndrome.They are different from choroid plexus papillomas.
The first symptoms of a choroid plexus carcinoma may, therefore, be pressure headaches, particularly in the mornings.
