A prominent right hilum is an enlargement of the root of the lung. It may exist naturally due to normal variation of the structure, or it may be caused by a disease.
Uncovering the underlying cause of a prominent right hilum may require the use of several tests, including CT and lab tests. A specialist, such as a pulmonologist, takes a full collection of signs and symptoms.
The hilum of the lung, which is also known as the root of the lung, is a triangular depression located just above the mediastinal surface and behind the cardiac impression of each lung.
