G306(P) A rare case of congenital left lung aplasia diagnosed antenatally

Abstract

tracheobronchitis. She was commenced on Rituximab and a six-month course of Cyclophosphamide.CT Neck and thorax showed focal obliteration of the airway at the level of hypopharynx and narrowing of left main bronchus. CT bronchogram showed the narrowing improved on a PEEP of 12 cm H2O. She was trialled on BiPAP overnight which helped her symptoms. She was referred to Great Ormond Street Hospital for a review; no further changes in management were suggested.The patient had recurrent relapses needing intensive care, therefore she was started on methotrexate and adalimumab, and had a balloon dilatation for her subglottic oedema and stenosis, which she tolerated well. She has been discharged home on overnight BiPAP with a plan for monthly balloon dilatations with ENT and to continue on methotrexate and adalimumab with gradual wean of steroids. Conclusion RP is rare with estimated incidence of 3.5 per million, only 10% cases are seen in paediatrics. Without aggressive and prompt treatment, life-threatening complications can develop rapidly, and outcomes are poor. Managing children with RP with significant airway involvement with NIV and repeated monthly balloon dilatations can help prevent life threatening exacerbations and the need for a tracheostomy. This case demonstrates the importance of multidisciplinary management of this complex condition.
