Presentation
Chronic diarrhea and unspecified abdominal pain.
Patient Data
Diffuse circumferential increased wall thickness is present in the colorectal, accompanied by mild surrounding fat-stranding and mesenteric vascular engorgement.
Multiple mesenteric and para-aortic prominent lymph nodes are also seen.
Extra and central intrahepatic bile ducts are dilated, and CBD measured 10 mm in caliber.
The patient underwent a colonoscopy and biopsy, and histopathology evaluation confirmed inflammatory bowel disease (ulcerative colitis).
Case Discussion
The primary cause of pancolitis is usually ulcerative colitis, although pseudomembranous colitis and other types of infective colitis may also be considered. In severe cases, the colon becomes atonic, with significant dilatation, exacerbated by bacterial overgrowth. This results in a toxic megacolon, which, while rare, has a grim prognosis.
