Abstract
Choroid plexus carcinoma is a rare intracranial neoplasm, affecting mainly very young
children. The most common site of origin is within one of the lateral ventricles.
The diagnosis of choroid plexus carcinoma is based on histological examination. Frequently
subarachnoid seeding occurs and investigation at diagnosis should include examination
of the cerebrospinal fluid and magnetic resonance imaging of the spinal cord. Extraneural
metastases are rare.
Prognosis for long-term survival ameliorates. Total surgical resection of the tumor
should be attempted. Both radiotherapy and chemotherapy are used as adjuvant therapies
for primary tumors. No clear difference in effectiveness of these therapies could
be found. However craniospinal irradiation seems to be more effective when leptomeningeal
seeding is present.
