CT findings and differential diagnosis of pseudomembranous colitis
Clostridium difficile is the primary pathogenic bacterium associated with pseudomembranous colitis(PMC).During an imbalance in the gut microbiota,Clostridium difficile proliferates and releases a large amount of toxins,leading to PMC.Diagnosis can be confirmed based on recent antibiotic use,diarrhea,and detection of Clostridium difficile pathogens or toxins.CT can assist in evaluating the extent and severity of the lesions.The CT manifestations of PMC overlap to some extent with other causes of colitis,but certain imaging features can help differentiate these conditions.This article provides a comprehensive review of the imaging features and differential diagnosis of PMC.
