CTICasesTuberculous Constrictive Pericarditis
Imaging findings
Cardiac MRI demonstrates severe thickening and abnormal delayed enhancement of the pericardium. Cine imaging during respiration reveals constrictive physiology, characterized by respiratory-dependent septal bounce and flattening of the interventricular septum, indicating ventricular interdependence.
Key takeaways
Tuberculosis is a classic and common cause of constrictive pericarditis, especially in endemic areas or in patients with a history of systemic TB infection. Cardiac MRI is a robust modality for assessing pericardial thickness, active inflammation via late gadolinium enhancement, and hemodynamic signs of constriction like respiratory-dependent septal bounce.
