Ulcerative colitis and perianal abscess

Case contributed by Dr Natalie Yang


Abdominal x-ray demonstrates a featureless descending colon, consistent with a "lead pipe" appearance. 


Abdomen and pelvis

Submucosal fat deposition (halo sign) and featureless colon (lead pipe sign) are both in keeping with chronic ulcerative colitis. Additionally a right sided perianal abscess is present. 

MRI similarly demonstrates submucosal fat deposition, and a right sided perianal abscess. 

Case Discussion

This patient with chronic ulcerative colitis developed a right sided perianal abscess. Perianal complications are much less frequently seen in UC than in Crohn disease... see Crohn's disease vs. ulcerative colitis
