Recent cases of intracranial tuberculomas

Area of Science:

• Neurology
• Infectious Diseases
• Oncology

Background:

• Intracranial tuberculomas are rare in developed countries.
• Tuberculosis (TB) can manifest as a central nervous system (CNS) mass lesion.
• Diagnosis can be challenging due to subtle or absent clinical signs of TB.

Observation:

• A study identified 12 patients with intracranial tuberculomas.
• Clinical findings suggestive of TB were often minimal or absent.
• Five patients lacked evidence of extracranial tuberculosis.
• Two cases presented as superinfected tuberculomas mimicking pyogenic brain abscesses.

Findings:

• Intracranial tuberculomas in this region primarily affect adults.
• Reactivation of dormant infection is the typical cause.
• Subtle presentation can delay diagnosis.
• Superinfection can alter the clinical presentation.

Implications:

• Increased awareness of intracranial tuberculomas is needed, even in non-endemic areas.
• Early diagnosis and treatment are crucial for favorable outcomes.
• Medical therapy, including chemotherapy, is the mainstay of treatment.
• Surgical intervention is reserved for specific complications like elevated intracranial pressure.
