Summary
Primary tuberculous meningitis can be diagnosed early using classic computed tomographic (CT) scan findings like basal meningeal enhancement and hydrocephalus. Early diagnosis enables timely antituberculosis treatment, improving patient outcomes.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Tuberculous meningitis (TBM) is a severe infection of the central nervous system.
- Early diagnosis and treatment are crucial for favorable outcomes.
- Radiographic findings play a vital role in TBM diagnosis.
Observation:
- This study presents five cases of primary tuberculous meningitis.
- Computed tomographic (CT) scans revealed basal meningeal enhancement, hydrocephalus, and arteritis in acute cases.
- Hydrocephalus and basal vessel arteritis were also observed in late-stage complications.
Findings:
- Classic CT scan findings, including basal meningeal enhancement and hydrocephalus, suggested early TBM diagnosis in three acute cases.
- These radiologic indicators prompted early initiation of antituberculosis treatment.
- Late complications also presented with hydrocephalus and basal vessel arteritis.
Implications:
- Correlation of clinical and radiographic findings is essential for prompt TBM diagnosis.
- Early diagnosis based on imaging can lead to timely treatment and potentially better prognoses.
- Understanding CT findings aids in managing tuberculous meningitis effectively.
