It was predominantly hyperintense on the T2-weighted images (Figure 1, Figure 2) and hypointense on the T1-weighted images (Fig. 3).
4-year-old boy with angiocentric glioma. High-resolution, T2-weighted image shows that the hyperintense, expansile lesion is predominantly cortical and lies anterior to the central sulcus.

It was predominantly hyperintense on the T2-weighted images (Figure 1, Figure 2) and hypointense on the T1-weighted images (Fig. 3).
4-year-old boy with angiocentric glioma. Postcontrast, axial, T1-weighted image shows no significant enhancement in the left posterior frontal lobe lesion.

fig4
It showed no significant postcontrast enhancement (Figure 4, Figure 5, Figure 6), restricted diffusion, or gradient susceptibility.
4-year-old boy with angiocentric glioma. Postcontrast, coronal, T1-weighted image shows no significant enhancement in the left posterior frontal lobe lesion. A small stalklike inferior extension is oriented toward the ventricle but does not reach the ventricular surface.

fig5
It showed no significant postcontrast enhancement (Figure 4, Figure 5, Figure 6), restricted diffusion, or gradient susceptibility. The lesion had a small stalklike extension that extended inferiorly toward the ventricle but did not reach the ventricular/ependymal surface (Figure 5, Figure 6).
4-year-old boy with angiocentric glioma. Postcontrast, sagittal, T1-weighted image shows no significant enhancement in the left posterior frontal lobe lesion. A small stalklike inferior extension is oriented toward the ventricle but does not reach the ventricular surface.

fig6
It showed no significant postcontrast enhancement (Figure 4, Figure 5, Figure 6), restricted diffusion, or gradient susceptibility. The lesion had a small stalklike extension that extended inferiorly toward the ventricle but did not reach the ventricular/ependymal surface (Figure 5, Figure 6).
4-year-old boy with angiocentric glioma. DTI image shows the corticospinal tract displaced posterior to the lesion, without any interruption or significant loss of volume.

fig7
On diffusion-tensor imaging, the corticospinal tract (CST) was seen to be displaced posteriorly by this mass lesion (Fig. 7), without significant interruption or loss of volume of the CST.
4-year-old boy with angiocentric glioma. Axial, noncontrast CT image shows that the lesion is iso- to hyperdense, without any calcification.
