Infantile thoracic tuberculosis

Case contributed by Dr Amr Farouk

Presentation

Repeated respiratory infections, fevers and failure to gain weight.

Patient Data

Age: 1 year
Gender: Male
Modality: CT

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.

Case Discussion

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.
