Summary

Solitary brain stem tuberculomas, rare infections mimicking brain tumors, present with non-specific neurological symptoms. Early diagnosis via CT-guided biopsy and treatment with antituberculous drugs lead to favorable outcomes.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Radiology

Background:

  • Solitary, intrinsic brain stem tuberculomas are rare and challenging to diagnose.
  • Neurological presentation often indistinguishable from other intrinsic brain stem masses.

Purpose of the Study:

  • To document the clinical presentation, management, and outcomes of intrinsic brain stem tuberculomas.
  • To highlight diagnostic challenges and therapeutic strategies for this uncommon condition.

Main Methods:

  • Retrospective analysis of six patients with histologically confirmed brain stem tuberculomas.
  • Diagnosis confirmed by CT-guided stereotactic biopsy.
  • Treatment involved antituberculous drugs and short-term steroid therapy.

Main Results:

  • CT scans showed ring-enhancing or nodular contrast-enhancing lesions.
  • All patients received 18 months of antituberculous therapy.
  • At follow-up (median 20 months), three patients were asymptomatic, and three had mild disability.

Conclusions:

  • Brain stem tuberculomas should be suspected in patients with intrinsic brain stem masses and contrast-enhancing lesions on CT.
  • CT-guided stereotactic biopsy aids in diagnosis, though etiology can be elusive.
  • Prompt diagnosis and treatment with antituberculous drugs and steroids generally yield excellent outcomes.
