Presentation
Right proptosis with loss of vision.
Patient Data
There is hypodense soft tissue mass centered on the right optic nerve in retrobulbar space, shows faint enhancement post-contrast, extend through the right optic canal to suprasellar cistern.
There is elongation with fusiform soft tissue mass in right optic nerve, which appears slightly hyperintense in T2W and FLAIR sequences, and shows homogenous enhancement in t1_vibe post-contrast. It extends posteriorly through right optic canal which is seen dilated, to suprasellar cistern. The optic chiasm is not seen separable from this lesion.
Case Discussion
Elongated with fusiform enhanced soft tissue mass in right optic nerve, extend through optic canal to involve optic chiasm in suprasellar cistern suggestive of optochiasmatic glioma.
