Abstract:
Tuberculomas in the form of multiple ring-enhancing brain lesions is an uncommon occurrence in immunocompetent patient. Central nervous system tuberculosis may manifest as meningitis, tuberculoma, or abscess and can even occur in patients with or without active respiratory tract infection. In the case of active infection, specific antibiotic combinations and dosing duration are required, and respiratory isolation/precautionary measures must be taken by the health care workers and members of the family. Most literature has reported Central nervous system tuberculosis in patients with immunosuppression such as from HIV infection or solid organ transplantation; however, in endemic areas, CNS tuberculoma should be a differential consideration even for immunocompetent patients presenting with ring enhancing lesion (s). Our case highlights the importance of maintaining this clinical suspicion. Early diagnosis and management of our patient helped prevent potentially serious neurological sequelae.
Insights
Central nervous system tuberculosis, though rare in immunocompetent individuals, can present as multiple ring-enhancing brain lesions. Maintaining clinical suspicion is crucial for early diagnosis and preventing neurological damage.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Central nervous system (CNS) tuberculosis is a significant cause of neurological morbidity, often associated with immunosuppression.
- It can manifest as meningitis, tuberculoma, or abscess, irrespective of active respiratory infection.
Observation:
- This case presents an immunocompetent patient with multiple ring-enhancing brain lesions, an uncommon presentation of CNS tuberculosis.
- Literature predominantly reports CNS tuberculosis in immunosuppressed individuals (e.g., HIV, organ transplant recipients).
Findings:
- Tuberculomas should be considered in the differential diagnosis of ring-enhancing brain lesions, even in immunocompetent patients, particularly in endemic areas.
- Early identification and treatment are vital for favorable outcomes.
Implications:
- Highlights the importance of considering CNS tuberculosis in immunocompetent patients with suggestive imaging findings.
- Timely diagnosis and management can prevent severe neurological sequelae and improve patient prognosis.
