Differential Diagnosis for Short Segment Transverse Colitis with Proximal Circumferential Wall Thickening
- Single Most Likely Diagnosis
- Diverticulitis: This condition is characterized by inflammation of a diverticulum, which is a small pouch in the wall of the colon. The presentation of short segment transverse colitis with proximal circumferential wall thickening is consistent with diverticulitis, especially if the patient has a history of diverticulosis.
- Other Likely Diagnoses
- Crohn's Disease: This is a type of inflammatory bowel disease (IBD) that can cause inflammation in any part of the gastrointestinal tract, including the colon. The transverse colon can be involved, and wall thickening is a common finding.
- Ulcerative Colitis: Although ulcerative colitis typically starts in the rectum and extends proximally in a continuous manner, it can occasionally present with skip lesions or a more limited segment of involvement, including the transverse colon.
- Infectious Colitis: Various infectious agents can cause colitis, including bacteria (e.g., Salmonella, Shigella), viruses, and parasites. The presentation can vary but may include segmental involvement and wall thickening.
- Do Not Miss Diagnoses
- Colon Cancer: Although less likely to present with acute inflammation, colon cancer can cause wall thickening and should be considered, especially in older patients or those with risk factors. It's crucial to rule out malignancy, as the treatment and prognosis are significantly different.
- Ischemic Colitis: This condition occurs when there is insufficient blood flow to the colon, which can lead to inflammation and potentially necrosis. It can present with segmental involvement and wall thickening, and it's essential to diagnose promptly due to the risk of complications.
- Rare Diagnoses
- Eosinophilic Colitis: A rare condition characterized by eosinophilic infiltration of the colonic wall, which can cause inflammation and wall thickening.
- Lymphocytic Colitis: A type of microscopic colitis that can present with chronic watery diarrhea and may have segmental wall thickening on imaging, although this is less common.
- Behçet's Disease: A rare form of vasculitis that can affect the gastrointestinal tract, including the colon, and cause inflammation and wall thickening.
