Abstract:
Extralobar pulmonary sequestrations are usually thoracic or abdominal lesions. A 29-week fetus demonstrated a 3.1 x 2.1 x 2.3 cm intrapericardial mass on ultrasonography. Magnetic resonance imaging demonstrated an extracardiac origin and suggested a pulmonary sequestration, which was confirmed after successful postnatal resection. Extralobar pulmonary sequestration should be considered in the presence of a fetal intrapericardial mass.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
