Left optic glioma. Orbits: There is fusiform enlargement up to 6 mm in diameter and tortuosity of the orbital segment of the left optic nerve with associated T2 hyperintensity, but no enhancement, with extension into the canalicular and cisternal segments of the left optic nerve. The optic chiasm does not appear to be involved and the right orbit is intact. Brain: There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma appears unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable.
The left optic nerve glioma appears to be unchanged.
