Summary
This case highlights a rare presentation of tuberculosis (TB) where typical symptoms and diagnostic tests were negative despite active infection. Early and thorough investigations are crucial for diagnosing pleural tuberculosis, even with atypical findings.
Area of Science:
- Pulmonology
- Infectious Diseases
- Medical Diagnostics
Background:
- Pleural tuberculosis (TB) can present with nonspecific symptoms, complicating diagnosis.
- Standard diagnostic indicators like tuberculin skin tests may be negative in active TB.
Observation:
- A 67-year-old male presented with bilateral pleural effusions and nonspecific symptoms.
- Initial tests, including tuberculin skin test and pleural fluid analysis, were inconclusive for TB.
- Pleural tissue cultures ultimately confirmed Mycobacterium tuberculosis infection.
Findings:
- The patient exhibited moderate anemia and severe lymphopenia.
- Pleural fluid analysis revealed an exudate with lymphocytic predominance but no acid-fast bacilli.
- Histological examination of pleural tissue showed no granulomas, contrasting with the positive mycobacterial culture.
Implications:
- This case underscores the importance of comprehensive investigations for unexplained pleural effusions.
- Diagnostic procedures should include pleural fluid and tissue cultures for mycobacteria, even with negative initial tests.
- Relying solely on classic symptoms or standard tests can lead to delayed diagnosis of pleural TB.
