A case report of an incidental finding of congenital oesophageal diverticulum in a patient presenting with stridor.

Congenital oesophageal diverticulum is incredibly rare and has not commonly been published in the literature. Oesophageal diverticulum can be asymptomatic; however, symptoms such as dysphagia, regurgitation and chest discomfort may be present. We describe the case of a paediatric patient presenting with biphasic stridor, respiratory distress and cyanosis at birth, who was found to have a supraglottic cyst and later the presence of an oesophageal diverticulum shown on ultrasound imaging. There has been one other case reported in the literature of an oesophageal diverticulum presenting with stridor, and we therefore believe this is one of only two cases to illustrate this atypical presentation of congenital oesophageal diverticulum. It highlights the importance of a meticulous multidisciplinary team approach to patient care, as well as conducting appropriate investigations to aid early diagnosis to improve patient outcomes.
