As outlined by Houdart et al. (1993), the depiction of intranidal aneurysms is difficult it is often performed at the time of superselective angiography. Moreover, true arterial intranidal aneurysms have to be distinguished from pseudoaneurysms, which are at the point of rupture of the nidus or of the venous drainage.
