RESUMO
A 32-year-old female presented with palpitations and chest discomfort. The patient had a history of pericardiotomy due to pericardial effusion. Multimodal imaging, including echocardiography, cardiac magnetic resonance (CMR), and coronary computed tomography angiography (CCTA) showed a single mass in the pericardium as the cause of the symptoms. Furthermore, its location and potential complications were accurately defined. The patient underwent a successful surgical resection of the pericardial cyst, microscopic histopathological examination was compatible with a bronchogenic cyst, a very rare congenital malformation. The article discusses the rarity of bronchogenic cysts in the pericardium and the importance of accurate diagnosis and appropriate treatment.
