Summary
Pulmonary tuberculosis presents with characteristic radiological findings like nodules and consolidation. Pathologic analysis of CT images aids in understanding the diverse morphology of this chronic granulomatous disease.
Area of Science:
- Radiology
- Pathology
- Pulmonology
Background:
- Pulmonary tuberculosis (TB) is a chronic granulomatous disease.
- Radiological findings include nodules, consolidation, cavitation, and calcification.
- Pathologically, it involves caseating granulomas or pneumonia with fibrosis and calcification.
Purpose of the Study:
- To correlate computed tomography (CT) findings with pathologic features of pulmonary tuberculosis.
- To elucidate the radiological manifestations of primary, postprimary, and miliary tuberculosis.
- To understand the evolution of pulmonary TB lesions with and without treatment.
Main Methods:
- Analysis of CT images.
- Pathologic correlation of radiological findings.
- Review of literature on pulmonary tuberculosis imaging.
Main Results:
- Primary TB shows consolidation with lymphadenitis.
- Postprimary TB manifests as apical nodular/linear opacities, centrilobular nodules, consolidation, cavities, and septal thickening.
- Miliary TB presents as well-defined, randomly distributed nodules.
- CT findings correlate with caseation, inflammation, fibrosis, and architectural distortion.
Conclusions:
- CT imaging provides crucial insights into the morphology of pulmonary tuberculosis.
- Understanding the radiologic-pathologic correlation aids in accurate diagnosis and management.
- CT findings reflect the underlying pathologic processes and treatment responses in pulmonary TB.
