Pericardial Effusion: Common Causes and Insights

Pericardial effusion is a relatively common clinical condition, often presenting with symptoms such as chest tightness and shortness of breath in the early stages of the disease. When patients visit the hospital, a cardiac ultrasound can easily detect the presence of fluid around the heart.

Understanding the Causes of Pericardial Effusion

There are numerous potential causes of pericardial effusion. Some of the most frequently observed include acute nonspecific pericarditis, pericarditis caused by malignancies, tuberculous pericardial effusion, and effusions triggered by various physical or chemical factors. Among these, tuberculous and cancer-related effusions are particularly prevalent.

Tuberculous Pericardial Effusion

Diagnosing tuberculous pericardial effusion can be challenging. In many cases, specialized tests such as fluid culture, pericardial fluid analysis, tuberculin skin tests, and interferon-gamma release assays (such as T-SPOT.TB) are necessary to accurately identify the underlying cause.

Malignancy-Related Pericardial Effusion

Effusions caused by cancer are also a significant concern, especially in patients with known or suspected malignancies. These effusions can result from direct tumor invasion or metastasis to the pericardium, and often require further imaging and laboratory evaluation to confirm the diagnosis.
