Learning objectives
1. To illustrate usual and unusual CT findings of abdominal tuberculosis2. To discuss the various imaging features that can differentiate from non-tuberculous abdominal diseases.
Background
Although tuberculosis is an endemic disease of developing countries, the global incidence of tuberculosis has increased and the number of the cases of extrapulmonary tuberculosishas also increased. Abdominal tuberculosis (Tbc) is an uncommon condition, but there has been a resurgence of the disease, becoming an endemic disease in most of the developing countries [1], largely due to the AIDS epidemic. So the interest in abdominal tuberculosis is increased with developing variable diagnostic or therapeutic modalities. However the diagnosis of abdominal tuberculosis still remains a diagnostic...
Imaging findings OR Procedure details
Tuberculosis of solid organs (liver, spleen, pancreas, kidney)
1.Liver and spleen
Involvement of the liver and spleen is common in miliary tuberculosis is and found in 80-100% of autopsied patients. However, it is usually in a fine miliary pattern and most of the time below the resolving capacity of CT [4]. Hepatosplenic tuberculosis may occur either often from pulmonary or miliary tuberculosis or through portal vein from GI lesions. This explains that the most common presentation is non-specific hepatosplenomegaly. Hepatosplenic tuberculosis develops under micro- or...
Conclusion
The correct diagnosis of abdominal tuberculosis is still remained challenging, as the clinical and radiological features have a wide range of spectrum, mimicking many other diseases, furthermore the imaging diagnosis is difficult, especially, in early stage of abdominal Tbc.CT imaging appears to be the imaging modality of choice in the detection and characterization of abdominal tuberculosis other than gastrointestinal Tbc.The CT findings that suggest abdominal tuberculosis include advanced ileocecal changes such as shortening of ascending colon, patulous ileocecal valve, circumferential wall thickening of terminal ileum...
