case_images: Echocardiography shows markedly thickened pericardium and abnormal soft tissue echoes anterior mediastinum.

case_images: Constrictive Pericarditis with markedly thickened Pericardium was appreciated ( Figure 1).
case_images: Magnetic resonance imaging shows diffuse pericardial thickening with only minimal amount of effusion.

case_images: The chest wall appeared normal ( Figure 2).
case_images: Cardiac magnetic resonance with intravenous contrast.. Short axis (
  A) and 2 chamber (
  B) images of steady-state free precession sequence demonstrating diffuse pericardial thickening with loss of normal interphase between the myocardium and pericardium (arrow). Short axis (
  C) and two-chamber (
  D) views of inversion recovery images obtained approximately 10 minutes after IV injection of gadolinium, showing diffuse pathological pericardial enhancement (arrows) and to a lesser extent epicardial enhancement and loss of normal myocardial - epicardial interphase (arrowhead).

case_images: The diagnosis was constrictive pericarditis with markedly thickened pericardium ( Figure 3).
case_images: The different views and sections of a computed tomography scan showing a markedly thickened pericardium and level 1 thoracic adenopathy.

case_images: Also observed were anterior mediastinal lymphadenopathy, moderate pleural effusion and associated atelectasis ( Figure 4). This should raise concern for neoplastic etiology ( Figure 4).
