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).

Histologic sample.
A and B, The neoplastic nature of the ganglion cell tumor's large neuron (straight arrow) is readily apparent when abnormal clustering and cytologic abnormalities, such as multinucleation and hyperchromaticia, are in evidence. Elsewhere this example harbored many atypical glial elements (curved arrow). Hematoxylin and eosin stain, light microscopy ×200 (A) and ×400 (B).
