Cystic artery pseudoaneurysm: A case report

Figure 1 Axial view of abdominal computed tomography. A: In the precontrast phase, the gallbladder is ill defined with areas of increased attenuation; B: In the arterial phase, pseudoaneurysm can be clearly observed as a well-defined hyperattenuated nodule (white arrow) inside the gallbladder with similar attenuation to aorta (*).

Figure 2 Sagittal views of contrast-enhanced abdominal computed tomography. A: A thin-walled gallbladder with wall enhancement (thin arrow) with common bile duct dilatation (thick arrow); B: A hyperattenuated pseudoaneurysm (white arrow) and atherosclerotic aorta (*).

Figure 3 Digital subtraction angiography. A: Celiac artery angiography showing common hepatic artery (thick white arrow), cystic artery (thin white arrow) and pseudoaneurysm (black arrow); B: Hyperselective cannulation of a branch of the cystic artery, showing the coil (thick white arrow) and pseudoaneurysm (black arrow); C: Pseudoaneurysm can no longer be observed after embolization. The coil is marked with white arrow.
