CTICasesCongenital Absence of Pericardium
Imaging findings
Cardiac MRI shows lung tissue insinuating itself between the main pulmonary artery and the ascending aorta, diagnostic of congenital partial absence of the left pericardium. The heart is shifted to the left.
Key takeaways
Congenital absence of the left pericardium is the most common pericardial defect. It allows the lung to herniate between the aorta and pulmonary artery, creating a characteristic contour abnormality on chest radiographs.
