lovebug  I know it's silly Q. but why not C) Granulomatous colitis? lol. thank you! +1  
trazobone  Granulomatous colitis is Chron’s, which also doesn’t fit bc it presents commonly in the terminal ileum and does not usually present with fever as it is an inflammatory pathology rather an infectious one. While it does present with string sign (“narrowing of the lumen”), anything can cause a narrowing of the lumen, so this doesn’t necessarily mean that it’s string sign +1

suckitnbme  Also agree the narrowing of the lumen plus the pic is pointing towards Crohn's. The acute systemic sx of fever and chills is what made me go with diverticulitis (along with the hx of increasing constipation). +1  
pg32  Why does the question say there is NARROWING OF THE LUMEN? Does that happen in diverticulitis? I went with Chron's at the last second against my better judgment because Chron's can cause strictures/narrowing of the lumen. +2  
lola915  FA 2020 pg.383 Most common area for Diverticulosis to take place is the sigmoid colon and diverticulitis can cause obstruction (inflammatory stenosis). The key here is recognizing the risk factors (>60, chronic constipation) and signs of acute inflammation (fever, chills and LLQ pain). +2

I would have easily chosen granulomatous colitis... had i known it is the same thing as Crohns. Shout out to ignorance and its bliss.

privatejoker  Does the obviously darkened area not point at all towards ischemia of any kind? Maybe I am blind, but I don't see anything that remotely looks like an obstructive diverticulum in this picture. I feel like I would have gotten this question correct if no picture had been provided at all because the symptoms described absolutely pointed towards diverticulitis otherwise. I actually changed my answer because of the image lol +19  
sahusema  Picture is a bullshit distractor +2  
lola915  From what I've seen on practice tests and advice i've gotten is that often if the picture is given along with an already complete clinical picture it's often a distractor. I also was going between ischemia and diverticulitis but then remembered that clinical signs in the vignette trump everything else. +1

quaper  I spent so long looking at that picture and thinking what the heck are they trying to show me here. I couldn't see any diverticuli, didn't see any cobblestoning, figured the dark patch in between the white patches was necrosis in the end. +8
