title: Migrating persistent pulmonary consolidation in a child: A case of follicular bronchiolitis.
abstract: Migrating pulmonary lesions in children are uncommon, and most are caused by eosinophilic lung disease and parasite, fungus, and tuberculosis infections. A 12-year-old boy was referred to our hospital because of an abnormal chest x-ray. Serial computed tomography scans performed over several months showed a migrating pulmonary consolidation in the left lung, although the patient remained asymptomatic. Finally, surgical biopsy was performed and follicular bronchiolitis was diagnosed. The consolidation disappeared 17 months later without treatment, and the patient has remained asymptomatic. Primary follicular bronchiolitis could be considered as one of the differential diagnosis in patients with pulmonary reticulo-nodular consolidation. It should also be noted that follicular bronchiolitis can migrate. Pediatr Pulmonol. 2017;52:E22-E25. © 2016 Wiley Periodicals, Inc.
