9-year-old male with optic nerve glioma, treatment with chemotherapy Orbit MRI: There has been no significant interval change in the minimally enhancing right orbital segment optic nerve glioma with a central cystic component, which again measures up to 7 mm in diameter. The other orbital contents are otherwise unremarkable. Brain MRI: There has been no significant interval change in a non-enhancing T2 hyperintense lesion centered within the left optic chiasm and hypothalamus that again measures up to 10 mm. Additional nonenhancing T2 hyperintense foci that localize to the more posterior portions of the bilateral optic tracks as well as a right periorbital gyrus are also unchanged. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The skull and scalp soft tissues are unremarkable. There is mild scattered paranasal sinus mucosal thickening. Mastoid air cells are clear. Expected vascular flow voids are demonstrated.
Unchanged bilateral optic pathway gliomas.
