A and B, Maximum intensity projection (A) and source (B) images of MRA showing a right internal carotid aneurysm (arrow). The distinction between intradural and extradural aneurysms is not clear. C and D, Coronal multiplanar reconstruction CE 3D-CISS images revealing that the aneurysm (large arrow) is extradural, located in the cavernous sinus. This observation was confirmed by surgery. The small arrow indicates the boundary between the cavernous sinus and the CSF.

Coronal multiplanar reconstruction images (A–C) of MRA show 2 left internal carotid aneurysms (arrow, asterisk). On CE 3D-CISS images (D–F), 1 aneurysm (asterisk) is assessed as extradural and the other (arrow), as partially intradural. Operative findings disclosed that they were extradural and intradural aneurysms, respectively.
