title: Posttraumatic pericardial cyst.
abstract: Pericardial cysts are uncommon lesions usually found incidentally upon the radiologic investigation of some other condition. The aetiology can be both congenital and acquired (post inflammatory processes, infection or even posttraumatic). They are the most common benign tumour of the pericardium but there is still a difficulty in the differential diagnosis because even clinical or analytically are not different from some other benign or malignant lesions. Further image studies are required to complete the study of these lesions. Even the majority are asymptomatic (>50%), the localization and relation to adjacent structures lead the role of the clinical manifestations (persistent cough, dyspnoea, chest pain...). We present the case of a man with oppressive chest pain after 2 weeks of thoracic traumatism with an abnormal radiological image in the chest X-ray.
