MRI Findings in Optic Nerve and Chiasmal Glioma in Childhood

Multiple cases of optic pathway gliomas are demonstrated using MRI imaging. The optic pathway gliomas are identified at multiple points in the optic pathways. Figure 1 : Patient 1: Axial orbital MRI (T1 postcontrast with fat suppression) showing thickening and enhancement of the right optic nerve and chiasm Figure 2 : Patient 1: Coronal orbital MRI (T1 postcontrast with fat suppression) showing enlargement and enhancement of the right optic nerve Figure 3 : Patient 2: Axial orbital MRI (T1 postcontrast with fat suppression) showing enlargement of the left optic nerve without enhancement Figure 4 : Patient 2: Axial orbital MRI (T1 postcontrast with fat suppression) showing enlargement of the optic chiasm without enhancement Figure 5 : Patient 2: Coronal orbital MRI (T1 postcontrast with fat suppression) showing enlargement of the optic chiasm without enhancement Figure 6 : Patient 3: Axial orbital MRI (T1 postcontrast with fat suppression) showing enlargement of the right optic nerve with enhancement Figure 7 : Patient 3: Coronal orbital MRI (T1 postcontrast with fat suppression) showing enlargement of the right optic nerve with enhancement Figure 8 : Patient 4: Coronal orbital/sella MRI (T1 postcontrast with fat suppression) showing a solid and cystic mass centered in the left hypothalamus and left optic chiasm Figure 9 : Patient 5: Coronal orbital/sella MRI (T1 postcontrast with fat suppression) showing a partially enhancing mass arising from the optic chiasm, with ventriculomegaly. Figure 10 : Patient 5: Coronal orbital/sella MRI (T2 weighted) showing a T2 hyperintense mass arising from the optic chiasm
