Massive Pericardial Effusion in a Case of Acute Pericarditis with Slight ST-Segment Elevation of Short Duration

ABSTRACT

We present the case of a 77-year-old woman who suffered from chest pain. Her white blood cell count was 10,200/μL and C-reactive protein level was 5.5 mg/dL. There was no electrocardiogram abnormality up to 5 hours after admission. At 15 hours, slight ST-segment elevation occurred, but this disappeared on day 4. Imaging revealed slight pericardial effusion. Nonsteroidal anti-inflammatory drugs and antibiotics were administered. However, the pericardial effusion, inflammatory response, and bilateral heart failure worsened. Pericardiotomy on day 6 released 350 mL of fluid, and symptoms improved. Viral pericarditis was assumed. Massive pericardial effusion is rare in cases of acute viral pericarditis, as is slight, short-duration ST-segment elevation.
