Imaging panorama of pediatric central nervous system tuberculosis

Central nervous system tuberculosis (CNS TB) is the most dreaded manifestation of systemic tuberculosis in the pediatric age group. It is associated with high morbidity and mortality due to severe neurological complications and sequelae. Knowledge about the imaging spectrum of CNS TB will help in early presumptive diagnosis and prompt treatment, reducing the development of complications. Imaging also plays a vital role in monitoring the progression of disease after the initiation of antituberculosis therapy. Advanced magnetic resonance imaging (MRI) techniques have recently improved the diagnostic efficacy manifold.In this review, we describe the imaging characteristics, the role of advanced imaging techniques, and follow-up imaging in various types of CNS TB in the pediatric population.
