case_images: The patient's electrocardiogram indicating sinus rhythm, a rate of 83 beats
  per minute with small voltage complexes, and nonspecific ST-T changes such
  as T-wave inversions in leads V5-V6, II, III, and
  aVF.

case_images: T-wave inversions in leads V5-V6, II, III, and (aVF) (Figure 1). The chest radiograph did not indicate any acute cardiopulmonary disease.
case_images: The patient's 2-dimensional transthoracic echocardiography on admission and
  outpatient follow-up: (A) Parasternal long-axis view:The red stars indicate
  the circumferential pericardial effusion on admission. (B) Apical 4-chamber
  view:The red star indicates the pericardial effusion on admission. (C)
  Parasternal long-axis view:There is complete interval resolution of the
  pericardial effusion on the 4-week outpatient follow-up visit. (D) Apical
  4-chamber view:There is complete interval resolution of the pericardial
  effusion on the 4-week outpatient follow-up visit.

case_images: fig2-23247096221140251
case_images: A 2-dimensional transthoracic echocardiogram (2D-TTE) revealed a moderate circumferential pericardial effusion ("anterior" dimension of 13 mm, "posterior" dimension of 8 mm) with no impending tamponade physiology and preserved left ventricular function (Figure 2). During his ensuing 1-week hospitalization, he remained hemodynamically stable, and a repeat 2D-TTE indicated a significant interval improvement in the pericardial effusion (Figure 2).
