The presence of a pericardial "halo" is a well-recognized sign of pericardial effusion when noted on a cardiac blood-pool study. The authors describe this finding on the early images of a biliary excretion study performed to evaluate mildly abnormal liver function tests. Correlative imaging studies subsequently confirmed the presence of a large pericardial effusion of rheumatoid origin.
