Intracranial choriocarcinoma

Intracranial choriocarcinomas are rare, accounting for only 5% of all pineal masses 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.

Pineal region masses

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.
