[Radiological imaging of pulmonary tuberculosis]

Area of Science:

• Medicine
• Radiology
• Infectious Diseases

Background:

• Pulmonary tuberculosis (TB) incidence is increasing globally after a period of decline.
• Radiological imaging is crucial for initial diagnosis but lacks definitive diagnostic power.
• Bacteriological confirmation remains the gold standard for diagnosing pulmonary TB.

Purpose of the Study:

• To describe the diverse radiological manifestations of primary and secondary pulmonary tuberculosis.
• To highlight the role of imaging in identifying key features of TB.
• To emphasize age-dependent variations in TB presentation.

Main Methods:

• Review of radiological findings in patients with confirmed pulmonary tuberculosis.
• Analysis of imaging characteristics associated with primary TB complex.
• Evaluation of secondary TB manifestations resulting from disease spread.

Main Results:

• Primary tuberculosis often presents as a primary complex (pulmonary infiltrate and hilar lymphadenopathy).
• Pleural effusion can be an isolated finding in primary TB.
• Age influences presentation: adults typically show consolidation, while children exhibit lymphadenopathy, potentially causing bronchial obstruction.

Conclusions:

• Radiological imaging is essential for suspecting and evaluating pulmonary tuberculosis.
• Understanding age-specific presentations and secondary manifestations improves diagnostic accuracy.
• Integrated approach combining imaging and bacteriology is vital for effective TB management.
