Aim:

To characterize a group of pediatric patients diagnosed with post-infectious bronchiolitis obliterans (PIBO) at a university hospital in Bogotá.

Methods:

A total of 2,635 PIBO-compatible clinical histories were reviewed. Pre-defined inclusion and exclusion criteria were applied, and 19 cases were retrieved and used to develop an observational, descriptive, and retrospective study.

Results:

The mean age for developing acute lower respiratory tract infection (ALRTI) was 18 months. The average hospitalization was 14.5 days, 21.5 % of patients required attention at a pediatric intensive care unit (PICU), and mechanical ventilation was applied for 10 % of these cases. A total of 30 % of the patients had microbiological isolation, 10.5 % corresponded to a respiratory syncytial virus (RSV), and 5 % corresponded to a mixed isolation (adenovirus and RSV). All patients had chest high-resolution computed tomography (HRCT) scans, which revealed a mosaic pattern of attenuation in 89.4 % of all cases.

Conclusions:

The sample showed clinical and radiological characteristics similar to those described in other case series worldwide.
