Asymptomatic congenital oesophageal cyst infiltrating the lung: an unusualcomplication

An asymptomatic 14-year-old boy presented with minor chest trauma. Chest X- ray showed opacity in the upper zone of the left lung. Further investigatio ns with magnetic resonance imaging showed it to be a posterior mediastinal mass with a fistula to the lung, along with cystic changes in the left uppe r lobe: of lung. Left upper lobectomy with excision of the: mass was perfor med. Histological examination later showed an oesophageal duplication cyst with a fistula to the left upper lobe of the lung. We present this unusual complication of an oesophageal cyst infiltrating the lung in an asymptomati c child. (C) 2000 Elsevier Science B.V. All rights reserved.
