Figure 1.

Cardiovascular magnetic resonance imaging performed day 9 of admission post-diagnosis of meningococcaemia (a) and (b) showing 4Ch view of normal left ventricular mass, size and systolic function. Normal global short-tau inversion recovery ratio suggests absence of myocardial oedema. (c) SAX view (T1-weighted image) late phase post-gadolinium showing a circumferential pericardial effusion. (d) 4Ch view with delayed gadolinium enhancement of visceral and parietal pericardium with probable subpericardial involvement consistent with myocyte injury and scaring caused by myocardial inflammation. 4Ch: four chamber; SAX: short axis.
