摘要
In this article, we report a 45-year-old female patient who was admitted with the complaints of cough, dyspnea and palpitation and referred to our clinic from Cardiology Outpatient Clinic due to tachyarrhythmia with a preliminary diagnosis of mediastinal mass. Thoracic computed tomography (CT) showed a smooth, lobulated contour and locally calcified cystic mass with a size of 7x6 cm in the right-sided middle mediastinum showing air-fluid level. The thorax was explorated from the fifth intercostal space with a right posterolateral thoracotomy incision. Exploration revealed a mediastinal mass originating from vena cava superior at the upper part and reaching the lower lobe. The mass was excised. The result of the histopathological examination was reported as a dermoid cyst containing hair, cartilage and sebaceous glands. We present this case as cardiac arrhythmia is a rare sign of mediastinal cysts.
