(a) Computer tomography scan and (b) MRI gradient sequence shows subarachnoid hemorrhage (arrows) in the perimesencephalic cisterns (c, d) Right and left internal carotid artery (ICA) angiograms show the fetal posterior cerebral artery PCA (arrows) (e) Pre-procedure vertebral angiogram on lateral view shows the fusiform aneurysm (arrow) of left SCA (f) Post-procedure vertebral angiogram on lateral view shows aneurysm was occluded completely (arrow) with endovascular coil embolization. (g) Control angiogram shows stable occlusion (arrow) of the aneurysm.

Control angiogram done at the end of 1 year showed stable occlusion with no re-canalization of the aneurysm [Figure 1d].

(a) Computer tomography scan shows the right cerebellar hemorrhage (arrow) and (b) digital subtraction angiogram (DSA) shows the fusiform aneurysm (arrow) of the right superior cerebellar artery (SCA). (c) Postprocedure angiogram reveals complete exclusion (arrow) of the aneurysm and (d) control angiogram shows stable occlusion (arrow) of the aneurysm.

CT scan done at admission showed acute right cerebellar hematoma [Figure 2a]. DSA done subsequently revealed fusiform aneurysm of the cisternal segment of the SCA [Figure 2b]. Endovascular treatment was done under general anesthesia with inside out coiling of the aneurysm with platinum coils [Figure 2c].

(a) Computer tomography scan shows acute subarachnoid hemorrhage in the superior cerebellar cisterns. (b, c) Digital subtraction angiograms (DSA) show the aneurysm from the distal superior cerebella artery (SCA) (d) DSA shows the aneurysm completely occluded with coils. (e) Control angiogram demonstrates stable occlusion of the aneurysm.

CT scan showed SAH in the superior cerebellar cisterns [Figure 3a]. SCA, predominantly involving the branch of the cortical segment [Figures 3b and c]. Standard heparin protocol was followed and an activated clotting time greater than 250 s was maintained during the procedure. 5F Envoy (cordis) guiding catheter was inserted in the distal vertebral artery. Post-procedure angiogram showed complete exclusion of the aneurysm along with the branch of the cortical segment and preservation of the flow in the superior cerebellar artery (SCA) [Figure 3d]. Control angiogram carried out after 1 year showed stable occlusion of the aneurysm with preservation of the ante-grade flow in the SCA [Figure 3e].
