Learning objectives
Tuberculosis can affect any organ system in the body and can be devastating if left untreated.
In this poster we discuss and illustrate the common imaging features of tuberculosis affecting genitourinary system.
The aim of this work is:
1- To recognise morphologic changes in genitourinary tract in different imaging techniques which make tuberculosis (TB) a possibility of diagnosis even when it is not suspected previously by clinicians.
It can affect:
*Kidneys, 75% unilateral,
(calcifications,
moth-eaten calyx -due to erosion which progress to papillary necrosis-,
infundibular...
Background
The increasing prevalence of tuberculosis in both immunocompetent and immunocompromised individuals in recent years,
makes this disease a topic of universal concern.
Tuberculosis has a variety of clinical and radiologic findings.
CT is specially useful in depicting genitourinary tuberculosis.
Diagnosis of GUTB (genitourinary tuberculosis) is often delayed owing to non-specific symptoms and insidious onset,
and because of its low prevalence in our continent until now.
Nevertheless,
the number of infected individuals is increasing over the world and GUTB is the second most common form of...
Findings and procedure details
We present five patients with GUTB,
(with microbiological,
anatomopathological or optimal response to tuberculostatics diagnoses),
one of them after BCG therapy.
None of them were initially suspected by clinicians.
In all cases,
radiologists suggested TB as the first possibility of diagnosis.
CASE 1
48 year old male.
AIDS positive.
Epididymal mass and symtoms of prostatitis.
Intravenous urography shows:

CASE 2

Conclusion
There are several imaging findings which make TB a great possibility even when it is not suspected by clinicians,
and consequently the radiologist plays an important role in the decision-making process.
A high degree of clinical suspicion and familiarity with the various radiologic manifestations of tuberculosis allow early diagnosis and timely initiation of appropriate therapy,
thereby reducing patient morbidity.
Currently,
not only the natural incidence of TB favoured by migration flows but also the secondary effect due to BCG therapy,
make TB an entity to...
