The finding of a chest X ray performed in a 59-year-old man as a routine diagnostic tool for preoperative assessment for inguinal hernia showed an asymmetric opacity in the superior mediastinum, eccentric to the right. CT of the chest was indicated and the obtained images showed the presence of right paratracheal cystic mass extending from sternoclavicular joint to azygos vein. Although the patient was asymptomatic, anterolateral thoracotomy with cyst extirpation was performed. Histopathologic evaluation revealed a cyst originating from parathyroid gland.
