Pancreatic Pseudocyst Pleural Fistula in Gallstone Pancreatitis

Figure 1

CT scan of the chest and abdomen demonstrating bilateral pleural effusions, the largest being in the left pleural cavity which is communicating directly with a pancreatic pseudocyst confirming the diagnosis of pancreatic pseudocyst-pleural fistula (PP-PF). Arrow A shows the position of the left pleural effusion communicating through fistula C with a large pancreatic pseudocyst D at the posterolateral aspect of the spleen B. Arrow E demonstrates the smaller right-sided pleural effusion.
