Pulmonary tuberculosis (TB) is a lung infection with varied radiological signs. Radiology is crucial for diagnosing TB, monitoring its complications, and guiding patient management.
Area of Science:
- Radiology
- Infectious Diseases
- Pulmonology
Background:
- Pulmonary tuberculosis (TB) is a prevalent global lung infection.
- Radiological findings in TB exhibit significant variation but are often diagnostic.
- TB is classically categorized into primary (childhood) and postprimary (adult) forms.
Purpose of the Study:
- To review the diverse radiological features of pulmonary tuberculosis.
- To highlight key imaging findings for primary and postprimary TB.
- To discuss the role of radiology in identifying TB complications.
Main Methods:
- Review of radiological manifestations of pulmonary tuberculosis.
- Correlation of imaging findings with disease stages and complications.
- Emphasis on computed tomography (CT) findings.
Main Results:
- Primary TB often shows lymphadenopathy, with enhanced CT revealing hypodense hilar/mediastinal nodes.
- Postprimary TB is characterized by cavitation (approx. 50% of cases) and consolidation in upper lobes.
- Radiology aids in detecting complications like miliary TB, pleural effusion, and late sequelae.
Conclusions:
- Radiological assessment is vital for diagnosing pulmonary tuberculosis.
- Imaging features help differentiate TB types and identify complications.
- Radiology plays a key role in managing and monitoring TB patients.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
