Intestinal tuberculosis (ITB) can mimic ulcerative colitis (UC), presenting a diagnostic challenge. Early identification of coexisting ITB and UC is crucial for effective treatment and improved patient outcomes.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Internal Medicine
Background:
- Intestinal tuberculosis (ITB) is a rare form of extrapulmonary tuberculosis.
- ITB frequently mimics inflammatory bowel diseases (IBD), complicating diagnosis.
- Ulcerative colitis (UC) is a common IBD that shares symptoms with ITB.
Observation:
- A 54-year-old woman with type 2 diabetes presented with chronic gastrointestinal symptoms.
- Initial investigations suggested IBD, but histopathology confirmed ITB.
- Despite anti-tuberculous therapy, symptoms persisted, raising suspicion for coexisting UC.
Findings:
- A subsequent colonoscopy revealed persistent inflammation, leading to a UC diagnosis.
- Combined treatment for ITB and UC resulted in significant symptom resolution.
- This case highlights the diagnostic complexity of overlapping ITB and UC.
Implications:
- Accurate differentiation between ITB and UC is essential for appropriate management.
- Coexisting gastrointestinal pathologies require timely recognition and integrated treatment strategies.
- Optimizing patient outcomes depends on addressing both infectious and autoimmune components.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Irritable Bowel Syndrome II: Clinical Features and Diagnostic Evaluation
Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
