Summary
Tuberculous meningoencephalitis (TBM) is a severe condition. Despite negative PCR results, continuing tuberculosis treatment improved patient outcomes, highlighting the need for clinical judgment.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Tuberculous meningoencephalitis (TBM) is a severe form of tuberculosis with high mortality.
- Rapid treatment initiation is crucial for survival, but definitive diagnosis is challenging, with only 40% of cases confirmed bacteriologically.
- Polymerase Chain Reaction (PCR) was expected to provide rapid and accurate diagnosis.
Observation:
- A case of lymphocytic bacterial meningoencephalitis with suspected tuberculous etiology is presented.
- The diagnosis was initially dismissed due to negative PCR results.
- Discontinuation of anti-tuberculosis therapy led to a significant decline in the patient's condition.
Findings:
- Restarting anti-tuberculosis therapy resulted in complete clinical remission after two months.
- Computed tomography revealed asymptomatic hydrocephalus despite clinical improvement.
- The case underscores the limitations of PCR in diagnosing TBM.
Implications:
- Clinical suspicion and response to treatment should guide TBM management, even with negative PCR.
- Anti-tuberculosis therapy can be effective even when initial diagnostic tests are inconclusive.
- This case highlights the importance of integrating diagnostic test results with clinical presentation in managing TBM.
