Pseudomembranous colitis

Case contributed by Dr Fakhry Mahmoud Ebouda


Patient with chronic kidney disease on haemodialysis with septic shock and type II respiratory failure on ventilator. Marked abdominal distension. CT to exclude intestinal obstruction.

Patient Data

Age: 70 years
Gender: Male

The positive contrast is seen passing through the entire bowel loops. Low attenuation marked bowel wall thickening and edema of the entire colon is seen more evident on the transverse colon with consequent encroachment upon the colonic interior lumen (luminal narrowing) and formation of crypt like appearance. The contrast is insinuated between the pseudo-membranes and swollen haustra creating an accordion sign. Noted marked ascites, pleural effusion and atropic kidneys.

Case Discussion

The CT findings are suggestive of pseudomembranous colitis in which Clostridioides difficile infection was the etiology.
