intracranial embryonal carcinoma
Magnetic
resonance imaging of pineal region tumours. Pineal embryonal carcinoma. The tumour involving the pineal gland (arrow) has lobulated margins with intermediate to high signal on axial T2-weighted image (a). The tumour shows heterogeneous contrast enhancement on sagittal T1-weighted image (b) related to its solid and cystic portions
An intracranial embryonal carcinoma is a relatively rare neoplasm and accounts for only 10% of all intracranial germ cell tumors . It is an aggressive tumor and has a propensity to metastasize systemically . A component of embryonal carcinoma is often found in mixed germ-cell tumors, in which case it is usually the most aggressive component, and dictates prognosis. CSF and plasma AFP and b-HCG may be elevated , but again this is not specific to this tumor.
