Infected pericardial cyst: a rare cause of neonatal cardiac tamponade, successfully treated by percutaneous aspiration

A 15-day-old term male neonate presented with respiratory distress, tachycardia, cyanosis (SpO2 85%), periorbital puffiness and pedal oedema (figure 1A). Echocardiography showed suprasystemic pulmonary artery pressures and a large (2.7x3 cm) mass compressing the right heart, producing cardiac tamponade (figure 1B; ). Saline contrast echocardiography (figure 1C; ) does not show any communication with the circulation. Contrast cardiac CT angiogram showed a large lobulated pericardial cyst encircling and compressing the right heart without any communication with the circulation (figure 1D). 3D CT reconstruction showed mass effect on the right heart structures (figure 1E). Echocardiography-guided fine needle aspiration of the cyst was performed with surgical backup. A 30 mL of pus was aspirated, and the culture showed methicillin-resistant Staphylococcus aureus growth. The workup for primary immunodeficiency was negative. After aspiration, the cardiac haemodynamics were normalised, and the neonate recovered with antibiotics. At...
