The hila consist of vessels, bronchi and lymph nodes. On a chest X-ray, abnormalities of these structures are represented by a change in position, size and/or density. Hilar enlargement. Hilar enlargement may be unilateral or bilateral, symmetrical or asymmetrical.


The dense hilum sign suggests a pathological process at the hilum or in the lung anterior or posterior to the hilum. Malignancy, especially lung cancer, should be suspected.. Radiographic features. On a well-centered chest posteroanterior (PA) radiograph the density of the hilum is comparable on both sides.


C: Increase in hilar density due to right hilar carcinoma. The right hilum appears denser than the left. This is often due to mass or enlarged nodes anterior or posterior to the hilum. The right hilum is also enlarged, with a subtle convexity in the hilar angle.


Thanks for your question on Health Care Magic. I can understand your concern. Yes, your CT findings can be due to toothache and tooth infection. Your CT findings are suggestive of lung Infection at hilum. Aspiration pneumonia is commonly seen in right hilum. Dental infections are common cause for...


The left hilum is commonly higher than the right Check the position, size and density of each hilum The lung roots, or hila (singular – hilum), are complicated anatomical structures containing the pulmonary vessels and the major bronchi, arranged asymmetrically.


2. Identify the hilar point: Look for the site where the most superior upper lobe vessel – either vein or artery – crosses the lateral margin of the little finger. The point of crossing is known as hilar point and forms a horizontal “vee” (> or <). Interpretation: The left hilum must never be lower than the right hilum.


A: A prominent hilar shadow on the chest x-ray of a 21 year old non-smoker suggests sarcoidosis, pulmonary hypertension or lymphoma. Other considerations include tuberculosis or a fungal infection,...


Anatomically, the hilum of an organ is the point of entry of the neurovascular bundle (arteries, veins and nerves) into an organ. In addition, the lymphatics and lymph nodes are typically along for the ride. On chest radiographs, the lung hila hav...


Summary Information: Hilar Lymph Nodes. Hilar Lymph Nodes: Hilar lymph nodes are glands that are a part of the immune system and are located where the lungs meet the bronchi. Hilar lymph nodes consist of lymphatic tissues enclosed by a fibrous capsule. They contain scavenging white blood cells that fight infection and its spread.


Enlarged lymph nodes in the hilum may occur in both the right and left hilum (bilateral lymphadenopathy) or on one side alone (asymmetric lymphadenopathy.) Causes may include: ung cancer : Lung cancer is the most common cause of unequal hilar regions in adults, both due to the presence of a tumor and to the presence of involved lymph nodes.
