Learning objectives
The objective of this study is to review the radiological findings we can observe in patients with abdominal manifestations of tuberculosis (TB),
in their various clinical presentations and localization,
with different imaging techniques: ultrasound,
intravenous urography,gastroduodenal study (GDS),
intestinal transit,
computed tomography (CT) and magnetic resonance (MR).
Background
Tuberculosis (TB) is an infection that is transmitted by air,
caused by mycobacteria,
Mycobacterium tuberculosis.
It is the most common cause of death from infectious diseases worldwide.
According to WHO,
2 million people die of TB every year and 6 million develop active disease.
In fact,
1/3 of the world population is considered carrier of TB (latent disease).
The incidence of this disease has resurfaced in non-endemic countries,
mainly due to immigration,
the HIV epidemic and resistance to antituberculosis drugs.
Various organs can be affected...
Imaging findings OR Procedure details
Several imaging techniques are included:
ultrasound,
intravenous urography,gastroduodenal study (GDS) and computed tomography (CT),
precontrast and with intravenous contrast (portal venous and delayed phases).
Conclusion
The clinical and radiological features of abdominal tuberculosis can mimic other diseases,
so we need a high degree of suspicion to get the right diagnosis.
Although in most cases the final diagnosis is microbiological (biopsy and / or culture),
it is convenient to know the radiological findings in order to be able to get an early diagnosis.
Early and adequate treatment prevents unnecessary surgery or even permanent sequelae.
