    Background: Pulmonary tuberculosis (TB) in children is characterised by mediastinal and hilar lymphadenopathy. Lymphobronchial TB (LBTB) describes the situation where tuberculous lymph nodes affect the airways by compression or erosion. Infants may be more susceptible to severe complications because of their specific airway anatomy and immature immune systems.

    Objective: The purpose of this study was to compare the computerised tomography (CT) findings of infants and children older than 12 months with LBTB to determine whether infants are more severely affected.

    Materials and methods: The CT scan reports of 98 children (< 13 years) with LBTB were reviewed retrospectively by a paediatric radiologist for a previous study. The relevant data were extracted from the existing database and the two age groups were compared with regard to lymphadenopathy, airway narrowing and parenchymal complications.

    Results: Of the 98 patients, 51% were infants. There was no statistically significant difference between infants and children (> 12 months) with reference to the frequency and distribution of airway compressions, lymphadenopathy and parenchymal findings. However, there was a statistically significant difference (p < 0.05) in the number of infants with complete compressions when compared to the older children.

    Conclusion: As opposed to older children, infants’ airways are more susceptible to complete airway compression as a result of LBTB. This is probably because of the airway size and anatomic development. We therefore recommend that infants presenting with symptoms of airway compression secondary to LBTB should be imaged urgently using CT scanning to ensure correct management.
