<unk> s are diagnosed using magnetic resonance imaging (MRI) and CT scans. The tumor adopts a fusiform appearance, appearing wider in the middle and tapered at the ends. Enlargement of the optic nerve along with a downward kink in the mid-orbit is usually observed. While CT scans allow for optic nerve evaluation, MRI allows for intracranial evaluation to observe if the tumor has extended to other regions such as the optic chiasm & hypothalamus.
