- Fig 1.
A, Right common carotid artery–injected angiography reveals a right extracranial ICA giant aneurysm. B, Left common carotid artery–injected angiography reveals a left extracranial ICA giant aneurysm.
- Fig 2.
A, Contrast-enhanced axial CT scan reveals focal bony defects bilaterally at the jugular foramen and hypoglossal canal with exophytic meningoceles (arrows). B, Contrast-enhanced axial CT scan reveals a right lambdoid suture defect (arrow). The drainage pathway of the right sigmoid sinus is noted to run aberrantly through the lambdoid sutures because of a space-occupying meningocele at the right jugular foramen.

A, Lateral view of the right cervical ICA taken with prolonged-injection angiography reveals an aneurysm (short arrow) and right aberrant jugular venous drainage (long arrow) through the lambdoid suture defect at the posterior neck. B, Venous phase of right carotid artery–injected angiography reveals bilateral sigmoid sinuses (arrows) running aberrantly through the lambdoid suture defects with aberrant jugular venous drainage.
