Malignant pericardial effusions is a condition when too much fluid builds up around the heart. A double-layered, sac-like structure surrounds the heart which is called pericardium. The space between the layers contains a fluid in a very small quantity.
But, when the pericardium becomes unhealthy or injured, it results into pericardial effusion. A fluid can also build up surrounding the heart without inflammation. At times the pericardial effusion can be caused by the accumulation of blood resulting from a surgical procedure or injury.
The pericardial effusions can be significant yet there can be no signs and symptoms, especially when the fluid has increased slowly.
But, when the symptoms do occur they may include:
When inflammation occurs in the pericardium caused by an injury, disease or inflammatory disorder, pericardial effusion takes place.
The condition may also occur when the flow of pericardial fluids is blocked or when blood accumulates within the pericardium. The clarity on how diseases play a role in the pericardial effusion cannot be determined though.
