The air-fluid level in cavitary pulmonary tuberculosis
Radiology
|May 1, 1978
Summary
Air-fluid levels in pulmonary tuberculosis cavities are uncommon but occur during active disease. This study highlights tuberculosis as a key consideration for lung cavities with air-fluid levels.
Area of Science:
- Pulmonology
- Infectious Diseases
- Radiology
Background:
- Pulmonary tuberculosis commonly causes lung cavities.
- Air-fluid levels within these cavities are considered unusual in tuberculosis.
Purpose of the Study:
- To report cases of active cavitary tuberculosis with air-fluid levels.
- To emphasize tuberculosis in the differential diagnosis of pulmonary cavities containing air-fluid levels.
Main Methods:
- Retrospective review of 18 cases.
- Analysis of clinical and radiological findings in active cavitary tuberculosis.
Main Results:
- 18 cases of active cavitary tuberculosis with air-fluid levels were identified.
- Air-fluid levels were observed during the active phase of the disease.
Conclusions:
- Tuberculosis should be considered in the differential diagnosis of pulmonary cavities with air-fluid levels.
- The pathogenesis of cavity formation in tuberculosis is discussed in relation to these findings.
