- Primary intracranial choriocarcinoma
Intracranial choriocarcinomas are rare, accounting for only 5% of all pineal masses 2 and 10% of all intracranial germ cells tumours 1. Like other intracranial germ cell tumours, they are found both in the pineal and suprasellar region. Typically they have increased CSF and plasma b-HCG, which are helpful in establishing the diagnosis 2,3.
Radiographic features
MRI Brain
These tumours are highly vascular and have a propensity to haemorrhage (as do their metastases). If present blood products may be evident on MRI as signal drop-out and blooming on T2* sequences and intrinsic high T1 signal, which needs to be distinguished from calcification and fat respectively 2.
They have a propensity to metastasise haematogenously 3.

The pineal region is anatomically complex and plays host to a number of unique masses and tumours as well as potentially affected by many entities seen more frequently elsewhere in the brain.
