Abstract: Our purpose was to present 3 cases of perineural tumor spread (PNS) to the oculomotor (CN III) nerve. To our knowledge, PNS to CN III has not been previously reported. In the course of advanced PNS, typically with involvement of the cavernous sinus, tumor may spread in a retrograde fashion to involve CN III in the interpeduncular fossa and can even invade the brainstem.
