A pericardial cyst is an uncommon benign dilatation of the pericardial sac surrounding the heart. It can lead to symptoms by compressing nearby structures, but is usually asymptomatic. [ 1 ] Pericardial cysts can be congenital or acquired, and they are typically diagnosed with radiologic imaging.
The sign is an imaging finding using a 3.5–7.5 MHz ultrasound probe in the fourth and fifth intercostal spaces in the anterior clavicular line using the M-Mode of the machine. This finding is seen in the M-mode tracing as pleura and lung being indistinguishable as linear hyperechogenic lines and is fairly reliable for diagnosis of a pneumothorax.
Secondary cancers: that have spread to the pericardium such as breast and lung cancer. Pericardial irregular thickening and/or nodularity, focal, or diffuse FDG uptake on PET scan and lack of preserved fat plane with an adjacent tumor are strongly suggestive of cancer spread from other parts of the body.

Purulent Pericarditis; Echocardiogram showing pericardial effusion with signs of cardiac tamponade: Specialty: Cardiology: Symptoms: substernal chest pain (exacerbated supine and with breathing deeply), dyspnea, fever, rigors/chills, and cardiorespiratory signs (i.e., tachycardia, friction rub, pulsus paradoxus, pericardial effusion, cardiac tamponade, pleural effusion)
After a routine ultrasound at 24 weeks, Brailey and Louis Valenzuela learned some unexpected news about their baby, Arley — she had an olive-sized tumor on her heart known as pericardial teratoma.
Pericardiocentesis should be performed with ultrasound guidance whenever possible to prevent complications. [2] [6] This allows practitioners to assess the location of the pericardial effusion and identify adjacent structures. [6] With ultrasound guidance, an apical approach is most often used, but parasternal and subxiphoid approaches can also ...
The diagnosis may be further supported by specific electrocardiogram (ECG) changes, chest X-ray, or an ultrasound of the heart. [2] If fluid increases slowly the pericardial sac can expand to contain more than 2 liters; however, if the increase is rapid, as little as 200 mL can result in tamponade. [2] Tamponade is a medical emergency. [5]
