This is a puzzling case, to be sure. I don't see the usual patterns & descript
ions one would find with UC (it almost always starts at the rectum and has continuous inflammation from there upward, sometimes just affecting the rectum; sometimes the rectum and sigmoid colon; sometimes rectum, sigmoid, and ascending; sometimes rectum, sigmoid, ascending, transverse; and finally, sometimes rectum, sigmoid, ascending, transverse, and descending, in which case it's called pancolitis.)
UC almost always has blood and usually has diarrhea.
ions of the CT scan results are more in line with Crohn's Colitis, which often skips the rectum and affects segmental sections of the colon, with healthy sections in between.
CT scans are quick but scopes are generally much better at diagnosing and distinguishing between UC and Crohn's Colitis. Biopsies are often key evidence, but sometimes they too are indeterminant. They, along with the pattern of inflammation (continuous vs. segmental) help distinguish, but sometimes it's just about
impossible to tell which it is.
Those CT scan results over the years make me wonder if he's had Crohn's for a number of years and it went undiagnosed for all that time. The CT at age 11 showing thickened transverse colon, the lymphadenopathy, etc, all point more to Crohn's than to UC.
The good news is that Entyvio is approved for either one.
