Tuberculosis (TB) is one of the top 10 causes of death worldwide and is the leading cause of death due to a single infectious agent. Globally, an estimated 10 million people fell ill with TB in 2019, of which 12% were children less than 15 years of age. TB in children is usually transmitted from adults and shows diverse radiological manifestations with variable presentation and rapid progression that are sometimes difficult to recognize. Both pulmonary and extrapulmonary TB are seen in children with a higher incidence of extrapulmonary TB than adults, particularly in developed nations. Pulmonary TB comprises 60–80% of pediatric tuberculosis cases worldwide. Among the extrapulmonary manifestations, lymphadenopathy is the most common (67%), followed by CNS involvement (13%), pleural (6%), miliary and/or disseminated (5%), skeletal (4%), and genito-urinary TB.

Educational Goals / Teaching Points
This exhibit aims to describe the diverse spectrum of presentation of TB in the pediatric population; describe the role of various imaging modalities in the evaluation of pediatric tuberculosis; highlight the occurrence of atypical and uncommon imaging findings in pediatric tuberculosis; and discuss the conditions masquerading TB on imaging among the pediatric population.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit provides a comprehensive discussion of various presentations of pediatric TB; illustrates the pulmonary and extrapulmonary manifestations of pediatric TBl highlights the uncommon presentations of pediatric TB; discusses the non-tubercular conditions that mimic TB in children; And illustrate the role of conventional imaging modalities and advanced imaging sequences in the diagnosis of TB and its complications.

The purpose of this exhibit is to illustrate the common and uncommon radiological patterns of involvement in pulmonary and extrapulmonary TB in the pediatric population. The presentation will describe the role of imaging and image-guided interventions in pediatric TB and highlight the difference in the presentation of TB in pediatric and adult populations. Lastly, this educational exhibit will discuss the various entities that can radiologically masquerade as pediatric TB.
