Differential Diagnosis for Ascending Colon Wall Thickening

Single Most Likely Diagnosis

  • Crohn's Disease: A type of inflammatory bowel disease (IBD) that can cause wall thickening in any part of the gastrointestinal tract, including the ascending colon, due to chronic inflammation.

Other Likely Diagnoses

  • Ulcerative Colitis: Although it typically starts in the rectum and extends proximally, ulcerative colitis can cause colon wall thickening, including in the ascending colon, especially in pancolitis.
  • Colon Cancer: Malignant tumors can cause wall thickening due to the growth of cancer cells in the colon wall.
  • Diverticulitis: Inflammation of a diverticulum in the colon wall can lead to localized wall thickening.
  • Infectious Colitis: Certain infections (bacterial, viral, or parasitic) can cause inflammation and subsequent wall thickening in the ascending colon.

Do Not Miss Diagnoses

  • Ischemic Colitis: Reduced blood flow to the colon can cause wall thickening and is a medical emergency that requires prompt diagnosis and treatment to prevent tissue death.
  • Pneumatosis Cystoides Intestinalis: A condition characterized by the presence of gas-filled cysts in the intestinal wall, which can be associated with various conditions, including ischemia and necrosis.
  • Intussusception: A condition where a part of the intestine telescopes into another part, which can cause bowel obstruction and wall thickening, requiring urgent intervention.

Rare Diagnoses

  • Eosinophilic Colitis: A rare condition characterized by eosinophilic infiltration of the colon wall, leading to inflammation and wall thickening.
  • Lymphoma: A type of cancer that can affect the immune system and cause wall thickening in the colon.
  • Amyloidosis: A condition characterized by the deposition of amyloid proteins in various tissues, including the colon, which can lead to wall thickening.
  • Graft-Versus-Host Disease (GVHD): A complication of allogeneic hematopoietic stem cell transplantation that can cause inflammation and wall thickening in the gastrointestinal tract, including the ascending colon.
