Multiple enlarged bilateral hilar and mediastinal as well as left supra-clavicular lymph nodes are seen showing heterogeneous enhancement with dominant low attenuation.
Left bronchial obstruction caused by the hilar lymphadenopathy is seen with mass-like consolidation of the left lung being slightly volume expanding and showing multiple low-attenuation areas within the consolidation area as well as associated left pleural effusion. Middle lobe subsegmental consolidation is seen as well.
Mediastinal lymphadenopathy with or without parenchymal abnormality is a radiologic hallmark of primary tuberculosis in childhood, and the most frequent radiographic finding of pulmonary parenchymal tuberculosis is consolidation.
The mediastinal lymph nodes were biopsied and showed tuberculous granulomatous lymphadenitis.
