FIGURE 2 Imaging of splenic artery aneurysm. A, Abdominal computed tomogram with intravenous contrast shows a 4-cm splenic artery aneurysm, with peripheral calcification, located at the splenic hilum (arrow). Arrowhead indicates the abdominal aorta. B, Splenic arteriogram from the same patient shows 2 large aneurysms (arrows) arising from the splenic artery. Distal aneurysm is 2 × 3 cm in diameter, and the proximal larger one is 4 cm in diameter. Segmental branches can be seen arising from the distal aneurysm. Arrowhead indicates the catheter in the splenic artery. C, Splenic artery aneurysm (arrow) appears as an extrinsic mass lesion on the posterior wall of the proximal stomach on upper gastrointestinal tract endoscopy. D, Endoscopic ultrasonography confirmed that the mass was a splenic artery aneurysm (arrow). E, Magnetic resonance angiogram shows a saccular aneurysm (2 × 3 cm) (arrow) of the superior mesenteric artery; aneurysm contains peripheral thrombus. Arrowhead indicates the abdominal aorta. F, Angiogram in this patient shows the aneurysm (arrow) of the proximal superior mesenteric artery.

FIGURE 3 Imaging of hepatic artery aneurysm. A, Doppler ultrasonography shows a hepatic artery aneurysm (4-5 cm in diameter) with laminated thrombus (arrow). B, Abdominal computed tomogram with intravenous contrast shows that the hepatic artery aneurysm is 4 cm in diameter (arrow). Curved arrow indicates the abdominal aorta, which has evidence of dissection. Arrowheads indicate a hepatic abscess. C and D, Celiac arteriogram shows the common hepatic artery aneurysm (arrow) before (C) and after (D) embolization. Curved arrow (C) indicates a liver abscess being drained with a catheter.
