REPORT OF AN ANTERIOR MEDIASTINAL CYST PRESENTING IN THE FORM OF PROLONGED CHEST PAIN

The authors report a case of anterior mediastinal cyst discovered incidentally in a 71-year-old man presenting with prolonged chest pain and a history of chronic renal failure secondary to polycystic kidney diseae. The diagnosis of these cysts, which are begign congenital tumours usually asymptomatic and with a favourable course, was established by thoracic CT. In difficult cases, magnetic resonance imaging allows precise analysis of pericardial masses. Clinicians should think of this possibility in the presence of an opacity of the cardiophrenic angla associated with chest pain.
