An unusual presentation of bronchiolitis obliterans in an adolescent

SummaryBronchiolitis obliterans usually follows severe lower respiratory tract infection and is a rare complication in children. We present a case of an adolescent who presented in an insidious manner following Mycoplasma pneumoniae infection. Further investigations demonstrated co-infection with adenovirus. Attempts at medical treatment made no difference and she was left with severely reduced lung function (FEV1 23% predicted). She is likely to require lung transplantation at some stage, although the timing and risks of transplantation need careful consideration.
