Chest imaging in a 2-year-old girl with pulmonary tuberculosis. a Posteroanterior chest radiograph (CXR) shows pneumonia of the right upper lobe. Note the displacement of the trachea towards the left and attenuation of the bronchus intermedius suggesting paratracheal lymphadenopathy. b Lateral CXR shows inferior bulging of the horizontal fissure and soft tissue density of lymphadenopathy around the carina. c A post-contrast axial computed tomography image (mediastinal window) demonstrates large volume lymphadenopathy of low density and peripherally enhancing lymph nodes (arrow). The right upper lobe is expanded and of predominantly low density, consistent with caseous necrosis. There is a small associated pleural effusion
