Introduction:
Large sphenoid ridge meningiomas are surgically challenging because of their extension to adjacent structures. Extracranial meningiomas are very rare; most are of the secondary type and have an intracranial origin. Improved surgical methods are required for treatment of this entity.
Presentation of case:
Here, we describe a case of a huge sphenoid ridge meningioma extending into the sphenoid sinus that was resected by staged transcranial and endoscopic endonasal resection via a transsphenoidal and transpterygoid approach. It was possible to excise the tumor from the sphenoid sinus in a minimally invasive manner via this approach.
Discussion and conclusion:
The transsphenoidal and transpterygoid approach was useful for providing a surgical field that allowed adequate visualization for removal of a sphenoid tumor that had expanded well into the lateral fossa of the sphenoid bone.
