  • Fig. 1 Aplasia of the internal carotid artery (ICA) with Dandy-Walker variant. A: T1-weighted sagittal magnetic resonance imaging (MRI) showing a hypoplastic cerebellar vermis (long white arrow). B: T2-weighted axial MRI revealing a paraclinoidal aneurysmal appearance (short white arrow). C: Computed tomography (CT) scan showing a large posterior fossa cyst and thinning of the occipital bone. D: CT scan disclosing a pneumatized canal (asterisk). E: Right carotid arteriography revealing absence of the ICA.
