pneumobilia vs portovenous gas

Pneumobilia and portal venous gas are two causes of an intrahepatic branching gas pattern. The two have different causes and implications and need to be distinguished on imaging, and a simple mnemonic can help.

Mnemonic

A simple mnemonic for remembering the difference in appearance is:

• portal venous gas: peripheral
• common bile duct gas: central
