(a) Computed tomography scan of the head demonstrating subarachnoid hemorrhage mainly in the left sylvian fissure. (b) Left carotid angiogram showing a saccular aneurysm (arrow) at the C1 portion of the left internal carotid artery without the typical angiographic appearance of dissecting aneurysm such as focal irregularity of the vessel wall and fusiform dilatation

Computed tomography (CT) of the head revealed SAH [Figure 1a] and cerebral angiography showed a saccular aneurysm at the C1 portion of the left internal carotid artery (ICA) [Figure 1b].

The patient underwent emergent clipping of the typical saccular aneurysm which had no features of dissection [Figure 2].
(a) Oblique coronal maximum intensity projection image of the abdomen demonstrating intraabdominal hematoma (white arrow) around the splenic artery aneurysm (black arrow) and common hepatic artery aneurysm (dotted arrow). (b) Three-dimensional computed tomography angiogram of the abdomen showing multiple aneurysms with the characteristics of dissection of the splenic artery (large arrow), gastroduodenal artery (arrowhead), common hepatic artery (dotted arrow), and superior mesenteric artery (small arrow)

CT of the abdomen revealed massive hematoma in the abdominal cavity around a splenic artery aneurysm, suggestive of the origin of bleeding [Figure 3a]. In addition to this lesion, three-dimensional CT angiography of the abdomen showed multiple aneurysms involving the gastroduodenal artery, common hepatic artery, and superior mesenteric artery [Figure 3b].
