ABSTRACT

Descreve-se uma apresentação rara de bronquiolite obliterante associada a hemossiderose pulmonar, em paciente de nove anos com sintomas respiratórios persistentes iniciados após episódio de bronquiolite aguda grave aos sete meses. Após o episódio agudo, apresentou sintomas respiratórios persistentes, piorando significativamente aos sete anos, quando começou a apresentar dificuldade respiratória em pequenos esforços. A tomografia computadorizada de tórax demonstrou achados compatíveis com bronquiolite obliterante. A biópsia pulmonar a céu aberto demonstrou numerosos macrófagos corados com hemossiderina, além dos achados compatíveis com bronquiolite obliterante. O diagnóstico de hemossiderose pulmonar pode estar ocasionalmente associado a bronquiolite obliterante em crianças com seqüela pós-viral grave.


In the present report, we describe an unusual presentation of post-infectious bronchiolitis obliterans accompanied by pulmonary hemosiderosis in a nine-year-old boy with persistent respiratory symptoms subsequent to an episode of acute bronchiolitis occurring at the age of seven months. After the episode, the persistent respiratory symptoms worsened significantly, and, by the age of seven, the patient began to have difficulty breathing after minimal exertion. Computed tomography of the chest presented findings consistent with bronchiolitis obliterans. Open lung biopsy revealed numerous hemosiderin-laden macrophages, as well as other findings consistent with bronchiolitis obliterans. Pulmonary hemosiderosis can occasionally be accompanied by bronchiolitis obliterans in children with severe sequelae after an episode of viral infection.
