What is the most common location of a pancreatic pseudocyst?

Show Suggested Answer Hide Answer
Suggested Answer: A

Pancreatic pseudocysts most commonly develop in the lesser sac, which lies between the posterior wall of the stomach and the anterior surface of the pancreas. This space allows for the accumulation of pancreatic fluid collections following pancreatitis or pancreatic ductal disruption.

The left anterior pararenal space (B) is a secondary location.

The right subdiaphragmatic space (C) and left pericolic gutter (D) are less common sites.

Really? I always thought it was more common in the right subdiaphragmatic space.

I’m pretty confident it’s the lesser sac, but I also recall something about the right subdiaphragmatic space being involved in some cases.

I’m torn between the lesser sac and the left anterior pararenal space. I wish I had reviewed this topic more thoroughly.

I remember practicing a question about pancreatic complications, and I feel like the left anterior pararenal space was mentioned there.

I think the lesser sac is the most common location for pancreatic pseudocysts, but I’m not completely sure.
