A 68-year-old male, presented with exertional dyspnoea and chest pain in his anterior chest wall for 3 months. He had no previous history of cardiac disease. Clinical examination failed to show anything significant. Chest X-ray showed a mass superimposed over the upper cardiac silhouette. He was further evaluated by chest CT, which showed a cystic mass in the anterior mediastinum measuring 9 x 7 cm in its maximum diameter. On surgical excision and histopathological examination, findings were consistent with benign pleuropericardial cyst, confirming the earlier diagnosis.
