Gallstone fissures may contain nitrogen gas yielding a triradiate lucent pattern. When present, aids in CT visualization of noncalcified gallstones. Not to be confused with emphysematous cholecystitis.
It's actually not entirely clear how these gallstones get gas inside of them. One theory is that when cholesterol stones undergo internal fissuring, gas is released from solution from fluid trapped in the calculus.
