PERICARDIAL CYSTS Meaning and
Definition
-
Pericardial cysts refer to fluid-filled sacs or cavities that develop within the pericardium, the protective membrane surrounding the heart. These cysts are considered rare benign congenital abnormalities, meaning they form during fetal development and are present from birth. The pericardium comprises two layers that surround the heart and help maintain its position within the chest cavity.
Pericardial cysts are typically small, measuring less than 5 centimeters in diameter, and are usually located in the middle mediastinum, the area between the lungs. They are often found by chance during routine imaging exams, as they usually do not produce noticeable symptoms. In some cases, however, larger cysts may cause chest pain, difficulty breathing, pressure on surrounding structures, or irregular heartbeat.
The exact cause of pericardial cysts is still unknown, but they are thought to result from developmental abnormalities during the formation of the pericardium. Although they are mainly harmless and do not require treatment, intervention may be necessary if the cysts become symptomatic or grow larger over time. Treatment options include surgical removal or aspiration of the cystic fluid.
While pericardial cysts are generally considered benign, it is essential to differentiate them from other cystic structures or tumors that may have significant implications for cardiac health. This distinction is typically made through medical imaging techniques such as echocardiography, computed tomography (CT) scan, or magnetic resonance imaging (MRI).

Etymology of PERICARDIAL CYSTS
The word "pericardial" is derived from the combination of two Greek words: "peri", meaning "around", and "cardia", meaning "heart". It refers to the membranous sac called the pericardium that surrounds and protects the heart.
The term "cysts" is derived from the Greek word "kystis", meaning "bladder" or "pouch". It is used to describe a sac-like structure that contains gas, fluid, or semi-solid material.
Therefore, "pericardial cysts" refers to the presence of cysts within or near the pericardium, the protective sac around the heart.
