A 16-year-old boy with a history of cardiac catheter ablation collapsed while wrestling. Following admission to the emergency department he underwent a contrast-enhanced CT scan of the chest (Fig. 1) and abdomen (Fig. 2). This showed a pericardial effusion, bowing of the interventricular septum, periportal edema, ascites, and IVC and right renal vein enlargement. Shortly after, he became hemodynamically unstable and underwent a pericardiocentesis with drainage of blood. He died a few hours after admission to the ICU.
Abdominal CT image at the renal level shows periportal edema, ascites, IVC and right renal vein enlargement
Cardiac tamponade results from heart compression and diminished cardiac output secondary to accumulation of fluid, pus, blood, gas or tissue within the pericardial cavity [1]. CT findings include pericardial effusion, cardiac chamber deformity, interventricular septum bowing, SVC and IVC distension, contrast medium reflux into the azygos vein and IVC, hepatic and renal vein enlargement, periportal edema and ascites [1, 2].
