"An intracranial embryonal carcinoma is a relatively rare neoplasm and accounts for only 10% of all intracranial germ cell tumours 1. It is an aggressive tumour and has a propensity to metastasise systemically 2. A component of embryonal carcinoma is often found in mixed germ-cell tumours, in which case it is usually the most aggressive component, and dictates prognosis. CSF and plasma AFP and b-HCG may be elevated 1, but again this is not specific to this tumour."
