Diffusion MRI also showed a change of blood stream in the left cavernous sinus, suggestive of thrombus.
Diffuse pachymeningeal enhancement involving the dura was noted, including asymmetric enhancement of the right cavernous sinus. Differential diagnosis included sinonasal metastatic disease or fungal sinusitis.
It is bordered at the many serious structures like cavernous sinus laterally, the eithmoidal air cells, anterior cranial fossa and optic nerve anteriorly, the clivus posteriorly, the hypophysis fossa and planum sphenoidale superiorly, choana inferiorly, internal carotid artery medially (Mamatha et al.; Seddinghi et al., 2014; Sevinc et al.; Farimaz et al., 2018).

It gives passage to an emissary vein that connects cavernous sinus with pterygoid venous plexus and a nerve known as 'Nervoulus sphenoidalis lateralis.' Accessory meningeal artery may pass through the foramen in 20% cases.
