An adult patient was diagnosed with purulent pericarditis, which is an infection of the pericardium (the fibrous sac surrounding the heart).
Two-dimensional transthoracic echocardiography revealed a significant reduction in the size of the right ventricular wall due to fibrin accumulation after treatment with a fibrinolytic agent.
This type of observation and measurement in an adult with purulent pericarditis hasn't been previously documented, marking a unique case in medical literature.
