ABSTRACT Our objective was to evaluate the incidence of colorectal tuberculosis in our series and to study its radiological spectrum. A total of 684 cases of proven gastrointestinal tuberculosis with positive barium contrast findings seen over a period of more than one decade were evaluated. The study did not include cases where colon was involved in direct contiguity with ileo-caecal tuberculosis. Seventy-four patients (10.8%) had colorectal tuberculosis. Commonest site involved was transverse colon, closely followed by rectum and ascending colon. Radiological findings observed were in the form of strictures (54%), colitis (39%) and polypoid lesions (7%). Complications noted were in the form of perforations and fistulae in 18.9% of cases. Colorectal tuberculosis is a very common site for gastrointestinal tuberculosis. Typical findings of colorectal tuberculosis are strictures, signs of colitis and polypoid lesions. Common complications are perforation and fistulae.

    • "Gastrointestinal tuberculosis can be identified in any age group and the presenting symptoms are generally nonspecific [2]. Isolated tuberculosis involvement in the colon is rare and constitutes 2-10.8% of all gastrointestinal tuberculosis cases [3] [4]. Diagnosis of patients with isolated colon involvement is highly problematic, especially in the absence of pulmonary infection. "

    ABSTRACT: Gastrointestinal tuberculosis occurs most often in the ileocecal region, but it can also occur in other locations in the gastrointestinal system. However, few cases with isolated gastrointestinal involvement have been reported. A 27-year-old female presented with abdominal pain, fatigue, weakness, weight loss, and anorexia. A mass was identified in her right lower abdominal quadrant on physical examination. Abdominal computed tomography (CT) showed a thickened right colon wall with marked narrowing of the lumen, and mucosal ulcers at the hepatic flexure and circular narrowing of the lumen 10cm distal to these lesions were identified on colonoscopic examination. Laparoscopic right hemicolectomy was performed due to the fact that malignancy could not be rule out. Gastrointestinal tuberculosis is often confused with inflammatory diseases, and even histopathological diagnosis is difficult in most cases. In addition to this, differentiation between malignancies and infectious diseases is also necessary.

    ABSTRACT: The purpose of this study was to describe the CT and MR imaging findings of tuberculosis of the gastrointestinal tract. Abdominal and pelvic CT scans and MRI studies of 6 patients with histopathological and microbiological proven intestinal tuberculosis were reviewed by two radiologists in consensus. Location and pattern of bowel wall involvement, signal intensities in relation to the normal bowel wall, pattern of enhancement and associated abdominal abnormalities were evaluated. Gastrointestinal tract tuberculosis may be limited to one bowel segment, with the cecum and ileocecal valve as the predominant site of disease, or may involve multiple bowel segments. Asymmetric thickening of the bowel wall is a common finding. Associated findings include pericecal and mesenteric fat stranding, regional lymphadenopathy showing peripheral, heterogeneous and/or homogeneous enhancement patterns and less commonly, tuberculous 'dry plastic' peritonitis. On magnetic resonance (MR) imaging, tuberculous bowel involvement results in intermediate decreased signal intensities on T1-weighted images, and intermediate increased, slight heterogeneous signal intensities on T2-weighted images. On contrast-enhanced images, slight heterogeneous enhancement is seen.

    ABSTRACT: . Despite the fact that major progress has been made in the development of new strategies for diagnosing and treating tuberculosis, the disease still remains a huge challenge for the world's health care. Numerous causes are responsible for this threat, but many of them cannot be resolved since a lot have cultural and social roots which cannot be changed easily. Furthermore, not all countries in the world have enough financial resources to provide essential support for their educational and therapeutic programs. One of the major challenges for tuberculosis is to deal with the growing and changing epidemic around the world, especially in the "low-income" countries. A new generation of clinicians as well as radiologists should be prepared to consider this "almost forgotten" disease as a new challenge at the beginning of this new millennium.
