(Left) Axial NECT through the
right iliac fossa in the same
patient demonstrates the
inflamed, distended appendix
ſt. Note the poor definition of
the wall and gas within the
lumen. (Right) Coronal MPR
NECT in the same patient
shows the increased density
and stranding in the
surrounding fat st and a tiny
focus of extra luminal gas ſt,
appearances representing
gangrenous appendicitis on
