1 Axial anatomic dissection, seen from above, shows the relationship of the right CNIII to the clivus and cavernous sinus dura. Axial anatomic dissection, seen from above, shows the relationship of the right CNIII to the clivus and cavernous sinus dura. The dura is dissected and retracted laterally to expose the arachnoid-lined CSF-filled OMC as it runs toward the anterior clinoid. Note the oblique orientation of the porus (modified and reprinted with permission from Martins et al1). K.L. Everton et al. AJNR Am J Neuroradiol 2008;29: ©2008 by American Society of Neuroradiology
