Toxic megacolon is seen in
up to 10% of patients with UC. Gaseous distention of the transverse
colon to beyond 6 cm is noted (although this is variable). Also note,
in this patient, that within the descending colon there is a band
of low-density corresponding to the submucosal edema and fatty proliferation,
both signs of UC. Toxic megacolon has up to a 30% mortality. |
