FIG 1. MR imaging of a 2-year-old boy with CP angle ganglioglioma.

A, T2-weighted axial MR image (4300/110/2 [TR/TE/excitations]). The mass shows relatively homogeneous high signal intensity (white arrow). The CSF cleft (black arrow) between the mass and the brain stem suggests the extraaxial origin of the tumor.

B, Precontrast T1-weighted axial MR image (366/11/3) shows a homogeneous low signal intensity mass in left CP angle compressing the brain stem.

C, Contrast-enhanced axial T1-weighted imaging shows no enhancement within the mass and a peritumoral vessel is visible (arrow).
