There can scarcely be any better comment on the difficulty in diagnosticating pericarditis with effusion than can be read out of statistics from the postmortem room. Even in institutions where the diagnostic work is admittedly of a high order, the postmortem findings of pericardial exudates entirely unsuspected during life is of not infrequent occurrence.
