Case in brief

A 61-year-old woman with a history of diabetes and an indwelling port-a-cath experienced sudden cardiovascular collapse and cardiac arrest following contrast administration during CT angiography. Imaging revealed a large pericardial effusion and superior vena cava thrombosis, indicating contrast extravasation into the pericardial sac. Emergent pericardiocentesis drained 1 L of fluid, leading to immediate hemodynamic recovery.

Diagnostic / clinical pearl

Clinicians should consider cardiac tamponade due to contrast extravasation in patients with central venous access devices who experience sudden cardiovascular collapse during contrast-enhanced imaging.
