- FIG 1.
A 4-year-old boy with a right cerebellar hemisphere YST. A, MR image shows the tumor located in the right cerebellar hemisphere. It is solid with cystic changes. B, There is a small amount of edema around the tumor, and the fourth ventricle is compressed. C, DWI shows isosignal of solid components of the mass. D, The tumor shows serpiginous enhancement.
- FIG 2.
An 11-year-old boy with a pineal region YST. A, MR image shows the tumor located in the pineal region with a slightly low signal associated with supratentorial dilation of the ventricle. B, The T2 sequence shows multiple, fine cysts with hypersignal (arrows). C and D, The DWI sequence and ADC map show that the tumor signal is the same as that of the cerebral cortex.
- FIG 3.
A boy, 2 years and 10 months of age, with a right cerebellar hemisphere YST. A, CT shows a slightly hypodense mass lesion accompanied by peritumoral edema. B, Enhanced CT shows heterogeneous density. C, H&E staining shows a typical Schiller-Duval body and loose, vacuolated network structures and prominent nucleoli with more atypia cells.
