Cases of the quarter: An unusual cause of chest pain in a young man: bronchogenic cysts and their cardiac manifestations

We report a case of a 24-year-old man who presented with chest pain and electrocardiographic evidence of myocardial ischaemia. An abnormal structure located  behind  the  heart  on  the  urgent  transthoracic  echocardiogram  and  a computed  tomography  scan  of  the  mediastinum  led  to  prompt  surgery  with eventual  resection  of  the  lesion. The  histology  revealed  fragments  of  connective tissue covered by squamous epithelium and ciliated epithelium, consistent with a bronchogenic  cyst. The  case  study  is  accompanied  by  a  literature  review  of  the pathogenesis,  diagnosis  and  management  of  bronchogenic  cysts  and  their association with cardiac symptoms.
