Sagittal anatomic dissection of the cavernous sinus with the dura partially removed and the oculomotor nerve exposed. Sagittal anatomic dissection of the cavernous sinus with the dura partially removed and the oculomotor nerve exposed. The lateral wall of the OMC has been removed to depict the nerve within the cistern. The OMC is outlined in green. The CNIII does not become incorporated into the fibrous dural cavernous sinus wall until it reaches the lower margin of the anterior clinoid process. Meckel cave is outlined in pink (modified and reprinted with permission from Martins et al1). K.L. Everton et al. AJNR Am J Neuroradiol 2008;29:1344-1348 ©2008 by American Society of Neuroradiology
