Isolated leptomeningeal tuberculoma.
Summary
Diagnosing intracranial tuberculomas can be challenging without systemic signs. Surgical biopsy is crucial for confirming Mycobacterium tuberculosis in suspected cases, even without widespread infection.
Area of Science:
- Neurology
- Infectious Diseases
- Pathology
Background:
- Intracranial leptomeningeal tuberculoma is rare and difficult to diagnose due to nonspecific symptoms.
- Systemic tuberculosis is often absent, complicating early identification.
Observation:
- A 49-year-old woman presented with focal seizures and weakness.
- Cranial MRI showed a left frontoparietal leptomeningeal lesion.
- Initial examinations did not reveal systemic tuberculous infection.
Findings:
- Histopathology confirmed caseating granulomas, suggestive of tuberculomas.
- Mycobacterium tuberculosis was cultured from the surgical specimen.
- Treatment with antituberculous agents led to lesion resolution.
Implications:
- Surgical biopsy is recommended for suspected intracranial tuberculosis, even without systemic evidence.
- Early diagnosis and treatment are vital for favorable outcomes.
- This case highlights the importance of considering tuberculosis in unexplained neurological lesions.
