hemopericardium
Post-infarction
full-thickness myocardial rupture: a life-saving CT diagnosis. Coronal reconstructed image from preliminary unenhanced acquisition revealed hyperattenuating (55 Hounsfield units) pericardial effusion (+) consistent with hemopericardium.
Post-infarction
full-thickness myocardial rupture: a life-saving CT diagnosis. Arterial-phase enhanced acquisition with bolus tracking technique showed contrast medium (*) extravasation through a full-thickness breach (Arrow) of the lateral wall of the left ventricle. Note hemopericardium(+), intra-aortic balloon pump(arrowhead).
Post-infarction
full-thickness myocardial rupture: a life-saving CT diagnosis. Coronal (C), sagittal (D), oblique (E) and 3D volume-rendering reconstruction (F) confirmed contrast (*) extravasation through a full-thickness discontinuity (arrow) of the left ventricular myocardium consistent with complete myocardial rupture.Note hemopericardium (+).
Post-infarction
full-thickness myocardial rupture: a life-saving CT diagnosis. Coronal (C), sagittal (D), oblique (E) and 3D volume-rendering reconstruction (F) confirmed contrast (*) extravasation through a full-thickness discontinuity (arrow) of the left ventricular myocardium consistent with complete myocardial rupture.
Post-infarction
full-thickness myocardial rupture: a life-saving CT diagnosis. Coronal (C), sagittal (D), oblique (E) and 3D volume-rendering reconstruction (F) confirmed contrast (*) extravasation through a full-thickness discontinuity (arrow) of the left ventricular myocardium consistent with complete myocardial rupture.Note hemopericardium (+).
Post-infarction
full-thickness myocardial rupture: a life-saving CT diagnosis. Additional venous phase acquisition showed increased opacification of the pericardial effusion (*) by contrast extravasation through the full-thickness rupture of the left ventricular myocardium (Arrow). Note hemopericardium (+).

Hemopericardium refers to the presence of blood within the pericardial cavity, i.e. a sanguineous pericardial effusion. If enough blood enters the pericardial cavity, then a potentially fatal cardiac tamponade can occur.
Pathology
Etiology
There is a very long list of causes but some of the more common are:
- ruptured myocardial infarction
- ruptured left ventricular aneurysm
- aortic dissection
- pericarditis
- trauma
- blunt/penetrating/deceleration
- iatrogenic, e.g. pacemaker wire insertion
- cardiac malignancies
- ruptured coronary artery aneurysm
- post-thrombolysis
Radiographic features
Plain radiograph
- enlargement of the cardiac silhouette may be present but chest x-rays are insensitive and non-specific
- the "straight left heart border" is an infrequent sign with low sensitivity (~40%) for hemopericardium in penetrating trauma patients
- the Oreo cookie sign on lateral CXR
CT
- pericardial effusion with a density >35 HU or that of water
Differential diagnosis
- vicarious contrast material excretion into the pericardium post cardiac catheterization may mimic hemopericardium on CT
