Four cases of developmental foregut cysts.

ABSTRACT

Four patients with developmental foregut cysts were seen in the Singapore General Hospital between 1991 and 1994. Three had bronchogenic cysts while one had features consistent with both enteric and bronchogenic origin. Among those patients with bronchogenic cysts, only one was symptomatic, having presented with cough and dysphagia. Two other patients presented incidentally on chest radiographs done for pre-National Service enlistment while one patient was picked up when a repeat chest radiograph was done following a course of antibiotics. The diagnosis of our first patient with the symptomatic bronchogenic cyst was based on barium swallow and a computerised tomographic scan of the thorax. Two patients were diagnosed on histology following open thoracotomy and surgical resection of the cysts to have a bronchogenic and a cyst of mixed origin as described above respectively. The last patient who underwent video-assisted thoracoscopic surgery with resection of the cyst was confirmed histologically to have a bronchogenic cyst.
