We present a case of diffuse constrictive pericarditis (CP) with multiple right and left ventricular wall outpouchings, simulating ventricular free wall aneurysm. Few cases have been reported till date of multiple ventricular free wall aneurysm-like outpouching adjacent to surrounding regions of thickened pericardium in a patient with CP.

| Introduction|| |
Constrictive pericarditis (CP) is caused by scarring and loss of elasticity of the pericardium, resulting in external impedance to cardiac filling resulting in heart failure. The most common causes of CP include viral or idiopathic pericarditis, previous cardiac surgery, and thoracic irradiation.
| Clinical Presentation|| |
A 34-year-old male patient presented with dyspnea and chest pain with a history of progressive right heart failure who was referred for cardiac computed tomography (CT) considering the possibility of CP. His physical examination was notable for marked jugular venous distension, abdominal fullness with significant ascites, and peripheral edema.
The patient underwent cardiac CT which reveals diffuse pericardial thickening [Figure 1], measuring approximately 5 mm with significant pericardial calcifications except at few focal regions through which ventricular free wall outpouchings are seen. Three well-defined focal outpouchings arising from the spared portion of the pericardium mimicking ventricular aneurysm are seen. The left ventricular aneurysm-like outpouching measured 3 cm × 1.7 cm, and the right ventricular outpouching measured 2.0 cm × 1.5 cm and 1.7 cm × 1.0 cm [Figure 2], [Figure 3], [Figure 4].

The heart appeared tubular in shape. Dilated hepatic veins and inferior vena cava demonstrated changes consistent with right ventricular overload [Figure 5]. There was no evidence of pericardial contrast enhancement.

Other imaging findings also seen in this patient included pulmonary thromboembolism with peripheral pulmonary infarcts and bilateral pleural effusion.
| Discussion|| |
The pericardium is a thin, avascular sac, which composes of two layers: an inner serous and an outer fibrous collagenous layer. Modalities such as CT and magnetic resonance imaging (MRI) provide excellent visualization of the pericardium. The thickness of the normal pericardium is <2 mm measured on CT or MRI. Pericardial thickness of 4 mm or more indicates abnormal thickening and, when accompanied with clinical findings of heart failure, is highly suggestive of CP.
CT has a high sensitivity in depicting pericardial calcification, which is also associated with CP. However, neither pericardial thickening nor calcification is diagnostic of CP unless the patient also has symptoms of heart failure. Other differentials which should be considered in patients with focal aneurysm include arrhythmogenic right ventricular dysplasia, acute myocardial infarction, acute myocarditis, and iatrogenic injury.
| Conclusion|| |
Our case very well demonstrates diffuse pericardial involvement consistent with CP with few focal region of sparing. The ventricular free wall that was covered with normal pericardium was not constricted and the adjacent thickened pericardium was stiff enough that this normal region protruded in between the edges of the thickened pericardium, simulating an aneurysm. The region of the ventricle that appeared abnormal and showed aneurysmal outpouching was normal-functioning portion with an overlying normal pericardium.
