Patient Data
Age: Child
Gender: Male
From the case:
Non-germinomatous germ cell tumor (pineal)

Axial T2
Large heterogeneous mass of the pineal region compresses the tectum and minor prominence of the ventricles. Intrinsic high T1 signal presumably represent blood products or proteinaceous material. It could also represent fat, and a fat saturated sequence would be required to confirm that this is not the case.
Case Discussion
Unfortunately, I do not have access to the formal histology report but I know that this was shown to be a non-germinoma germ cell tumor of the pineal gland. The options therefore are:
- pineal embryonal carcinoma
- pineal choriocarcinoma
- pineal yolk sac carcinoma
- pineal teratoma
