Focal lung hyperinflation in an infant: Not always congenital lobar hyperinflation - A case report

Lymphobronchial tuberculosis (TB) is particularly common in children and is characterized by tuberculous lymphadenopathy affecting the airways, leading to various radiological findings. Computed tomography (CT) is the preferred imaging modality for diagnosing lymphobronchial TB due to its ability to detect mediastinal lymph nodes and airway involvement. CT findings include lymphadenopathy, bronchial narrowing, and a range of parenchymal complications. We describe the case of a 1-year-old girl who presented with chest complaints and focal lung hyperinflation, which was subsequently proven to be due to lymphobronchial TB.
