Figure 2: 99mTc labeled hydrazinonicotinyl-Tyr3 (HYNIC-TOC) scan. Anterior planar image does show significant tracer uptake in the orbits [Figure 2]a. Single photon emission computed tomography/computed tomography (SPECT/CT) images [Figure 2]b and [Figure 2]c showed focal increased tracer uptake in ovoid lesion encasing the right optic nerve (thin white arrow). Post radiotherapy follow up MR showed interval decrease in the size of the lesion in enhancing lesion [Figure 2]d, bold white arrow].
