Cardiomediastinal refers to the mediastinum, which is the area between the lungs that contains the heart, esophagus and thymus. The term cardiomediastinal is an adjective that references bodily functions and disorders related to the heart and surrounding tissue.Know More
View the cardiomediastinal silhouette by x-ray or other medical imaging technique. It is important for radiologists to understand the physiology of the mediastinum for accurate diagnosis of abnormalities.
The mediastinum is comprised of three different regions. The anterior region is made up of blood vessels and lymph nodes. The middle region contains the heart. The posterior region has the esophagus.
If the cardiomediastinal silhouette is larger than expected, it is possibly due to cardiomegaly, which is an enlargement of the heart. Cardiomegaly is caused by a genetic inheritance or by high blood pressure.
Another cause of cardiomediastinal enlargement is pericardial effusion, a condition in which excess fluid enters the tissue surrounding the heart muscle. Pericardial effusion could be a sign of serious disease, including cancer, heart attack or trauma to the heart wall. It might also signify a viral inflammation of the heart tissue known as pericarditis. The best methods for detecting this condition include a chest x-ray of the cardiomediastinal silhouette and an echocardiogram, or ultrasound, of the heart.Learn more about Diagnostics & Imaging
To interpret a chest X-ray, it is necessary to know normal anatomy and possible anatomical deviations as well as diseases or pathologies of the heart, lungs, mediastinum (middle section of the chest cavity), lungs and pleura (thin tissue that lines the inside of the chest cavity). It is best to take a systematic approach, working from the inside out of the film, according to the Radiology Assistant.Full Answer >
The thoracic cavity protects and holds the lungs, heart, trachea, esophagus, endocrine glands, thoracic aorta and the pulmonary artery. Enclosed by the ribs, breast bone and vertebral column, it is the second-largest hollow space of the human body.Full Answer >
The essential organs contained within the thoracic cavity are the lungs, the heart, part of the esophagus, the trachea, the thymus gland and the thoracic duct. There are lymph nodes within the thoracic cavity, as well as numerous blood vessels and nerves. There are three compartments within the thoracic cavity: two pulmonary cavities and the mediastinum.Full Answer >
Esophagogastroduodenoscopy, or EGD, is a diagnostic test that allows doctors to examine and treat problems in the esophagus. The procedure involves passing a black tube, which has a camera at one end, through the mouth to view the esophagus, stomach and duodenum, the first portion of the small intestine.Full Answer >
