Atypical radiological manifestations of pulmonary Langerhans cell histiocytosis in a 12-year-old girl

Abstract

. Pulmonary Langerhans cell histiocytosis is a rare pulmonary disease that typically affects cigarette smokers from 30–40 years of age onwards. It is very rare in children, especially for those under 15 years of age. We report an atypical radiological manifestation of isolated pulmonary Langerhans cell histiocytosis in a 12-year-old girl that showed multifocal consolidation and multiple small nodules on an initial chest radiograph, and gradual fibrotic change with multiple cysts on follow-up chest radiographs and CT scans.
