Figure 1: Magnetic resonance image finding of the brain. (a) There is a heterogeneous tumor mass involving the pineal gland and the bilateral hypothalamus. This irregularly shaped tumor is iso- to hypointense to the cortex on the T2-weighted image. (b) An iso- to hypointense tumor with size 2.7 cm is demonstrated on the T2-fluid-attenuated inversion recovery image. (c) Besides, heterogeneous enhancement of the tumor is also noted on the T1-weighted image with the enhancement of gadolinium. (d) The prior heterogeneous tumor mass involving the pineal gland and the bilateral hypothalamus is not depicted and without any imaging evidence showing regional heterogeneous enhancement. There is no regional recurrence 12 months after surgical removal of tumor and radiotherapy
