CTICasesEffusive-constrictive pericarditis secondary to leukemia
Imaging findings
Cardiac MRI shows a complex septated fluid collection in the pericardial space with thickened, delayed-enhancing pericardial layers, ventricular tubular remodeling, and diastolic septal bounce (ventricular interdependence) that is more pronounced during inspiration. This presentation was secondary to acute myelogenous leukemia (AML).
Key takeaways
Effusive-constrictive pericarditis combines the physiology of cardiac tamponade (from fluid under pressure) and pericardial constriction. The hallmark of constrictive physiology on cardiac MRI is diastolic ventricular interdependence, visualized as a septal bounce that varies with respiration.
