Optic gliomas status post chemotherapy: off therapy evaluation. There is near interval resolution of enhancement and T2 hyperintensity in the left globus pallidus. Otherwise, there has been interval increase in size of multiple enhancing foci along the expected course of the bilateral optic pathways. For example, an enhancing component in the left lateral thalamic region measures up to 15 mm, previously 12 mm and a left postchiasmatic optic nerve focus of enhancement measures up to 7 mm, previously 5 mm. There is no significant interval change in the optic chiasm and intraorbital component of the optic nerve gliomas, right larger than left, with persistent mild enhancement of the orbital segment of the right optic nerve and marked dilatation of the right optic nerve sheath. There is persistent faint intrinsic T1 hyperintensity of the bilateral basal ganglia and cerebellar nuclei. There is no evidence of acute infarct. The ventricles are mildly prominent, which is unchanged. There is no midline shift. There is a nonspecific focus of enhancement of the skin and subcutaneous tissues of left cheek, which may be inflammatory in nature.
Near interval resolution of the enhancing lesion in the left globus pallidus, but interval increase in size of multiple enhancing lesions along the expected course of the bilateral optic pathways. Otherwise, no significant interval change in the optic chiasm and intraorbital components of the optic nerve gliomas, right larger than left
