Summary
Lower lung field tuberculosis, a form of pulmonary tuberculosis, was found in 10.3% of adult patients. This condition frequently affected younger women and was associated with pregnancy, HIV, and diabetes.
Area of Science:
- Pulmonology
- Infectious Diseases
- Radiology
Background:
- Tuberculosis (TB) typically affects the upper lobes of the lungs.
- Lower lung field involvement in pulmonary TB is less common but significant.
- Understanding the characteristics of lower lung field TB is crucial for diagnosis and management.
Purpose of the Study:
- To investigate the prevalence and characteristics of lower lung field tuberculosis in adult patients.
- To identify associated risk factors and clinical presentations of this TB form.
- To highlight the importance of considering lower lung field TB in differential diagnoses.
Main Methods:
- Retrospective study of 273 adult pulmonary tuberculosis patients admitted to Jamot Hospital, Yaounde.
- Analysis of patient demographics, clinical symptoms, and radiographic findings.
- Identification of associated conditions such as pregnancy, HIV infection, and diabetes mellitus.
Main Results:
- Twenty-eight cases (10.3%) of lower lung field tuberculosis were identified.
- The condition predominantly affected patients under 40 years old, with a higher incidence in women.
- Common radiographic findings included extensive consolidation (87.3%), with less frequent cavities and pleural effusion.
Conclusions:
- Lower lung field tuberculosis is an important diagnostic consideration, particularly in younger adults and women.
- Associated conditions like HIV and diabetes mellitus may increase susceptibility.
- Clinical and radiographic presentations can mimic upper lobe disease, emphasizing the need for high diagnostic suspicion.
