Learning objectives
-To detail the different manifestations of Tuberculosis.
-To demonstrate the effectiveness of various imaging modalities in the diagnosis of Tuberculosis.
Background
Tuberculosis is one of the top 10 causes of death in the world that can easily spread from one individual to another though air.
A rapid diagnosis and consistent therapy is crucial to prevent it from infecting other people and its resistance formation.
From a radiological perspective,
the first stage of identifying a possible tuberculosis infection is made via Thoracic X-rays.
The computer tomography is particularly helpful for the assessment of the disease activity and its associated complications.
Pathogen: Mycobacterium tuberculosis complex (MTBC).
Mycobacteria (genus...
Findings and procedure details
Primary tuberculosis (Figure 1,3,4,5,6)
o Round infiltrates and consolidations
o Especially right lung
o Especially basal lower lobe,
middle lobe and anterior upper lobe
o Lymph node enlargement (90 - 95% in children,
10 - 30% in adults)
o Obstructive atelectasis (up to 30%)
o Pleural effusion (5 - 10% in children,
30 - 40% in adults)
Anatomically the right bronchus bifurcates at an angle of about 70 degrees,
giving a greater volume and respiratory capacity to the right lung.(Figure 2)
For this reason,
primary...
Conclusion
Extrapulmonary tuberculosis is not always easy to identify.
An intestinal tuberculosis may be confused,
for example,
for an inflammatory bowel disease or a malignancy,
which may lead to unnecessary surgical procedures.
In the treatment of therapy-resistant pulmonary infiltrates consider tuberculosis as a possible cause.
Early CT (as X-rays are often negative) is recommended to confirm diagnosis.
Recovery may take months to years.
