CT scan . A: CECT axial venous phase showing chronic calcific pancreatitis (black arrow); B: Axial and C: Coronal maximum intensity projection arterial phase images showing hyperdense content (blood /clots) within the pseudocyst (asterisk) with evidence of pseudoaneurysm (white arrow) arising from the left gastric artery.

FIG1
The contrast-enhanced computed tomography (CECT) showed features of chronic calcific pancreatitis with a 5x6 cm pseudocyst in the lesser sac (Figure 1A). The pseudocyst was filled with hyperdense content (blood products/clots) associated with a pseudoaneurysm from the left gastric artery (Figures 1B, 1C).
Digital subtraction angiography. (a) Digital subtraction angiography (DSA) showing a pseudoaneurysm (arrow) arising from a first-order branch of the left gastric artery (LGA); (b) DSA showing a completely knocked-off first-order branch of the left gastric artery (LGA) without filling up of the pseudoaneurysm. The arrow indicates embolizing coils.

FIG2
It confirmed a pseudoaneurysm in the left gastric artery (Figure 2a). A post-embolization run showed no active contrast extravasation into the pseudoaneurysm (Figure 2b).
