What is an ill defined opacity of the lung? Answer by Kalopay 99. Confidence votes 155. On high-resolution CT of the lung, ground-glass opacity may represent a spectrum of diseases ranging from isolated interstitial abnormalities to isolated alveolar filling, and frequently represents entities involving both parenchymal compartments [1, 2, 3].

Chest X-Ray - Lung disease Publicationdate February 1, 2014. On a chest x-ray lung abnormalities will either present as areas of increased density or as areas of decreased density. Lung abnormalities with an increased density - also called opacities - are the most common. A practical approach is to divide these into four patterns: Consolidation. Interstitial.

What Does a Mass on the Lung Mean? What does a mass on the lung mean? A: A lung mass may indicate lung cancer, an abscess, a form of pneumonia, a sign of infection or an amalgamation of protein, notes About.com. Lung masses are defined as abnormal spots in the lungs larger than 3 centimeters; those less than 3 centimeters in diameter are known as lung 'nodules.'. Continue Reading.

Pneumonia lung opacity Read More. The diagnosis of a lung nodule depends on the symptoms you have, the size of the nodule, number of nodules and their shape and borders. A well defined solid opacity in lung can be due to pneumonia, cancer, tuberculosis, a benign lung nodule, or due to an infarct.

How to differentiate ground glass opacity from mosaic attenuation • This term mosaic attenuation is non specific and could include mosaic perfusion (mosaic oliagemia) or ground glass opacity. • Areas of decreased attenuation due to regional differences in lung perfusion = mosaic perfusion / oligemia = obstructive airway or vascular disease.

Lung scarring Lung scarring. Lung scarring: Introduction. Lung scarring: Damage to the lung tissue from and cause can cause scarring of the lung tissue. Small scars generally cause no problems but large or widespread scarring can affect breathing. Causes of lung scarring include pneumonia, lung infections, cystic fibrosis, asbestosis, silicosis and sarcoidosis and tuberculosis.

Definitions &Translations Freebase (0.00 / 0 votes) Rate this definition: Opacity. Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc.

An Overview of Bronchiectasis Bronchiectasis is a form of chronic obstructive pulmonary disease (COPD) in which the large airways of the lungs become damaged and widened. Mucous can collect in these dilated airways, allowing bacteria to grow and cause recurrent lung infections.

Pulmonary fibrosis Pulmonary fibrosis (literally scarring of the lungs) is a respiratory disease in which scars are formed in the lung tissues, leading to serious breathing problems. Scar formation, the accumulation of excess fibrous connective tissue (the process called fibrosis), leads to thickening of the walls, and causes reduced oxygen supply in the blood.

Pulmonary Nodules Pulmonary nodules are small, focal, radiographic opacities that may be solitary or multiple. A classic solitary pulmonary nodule (SPN) is a single, spherical, well-circumscribed, radiographic opacity measuring less than or equal to 30 mm in diameter and is surrounded completely by aerated lung. The SPN is a coined term that in the past described solitary nodules detected incidentally by chest radiography (CXR).

- Ground glass opacities on chest x-rays may be due to inflammatory or infectious causes, and occasionally hemorrhage . You may have or previously had a process causing the ground glass appearance. If you are having any symptoms, consult your internist or pulmonologist.

Lung Nodules A lung nodule is defined as a “spot” on the lung that is 3 cm (about 1 ½ inches) in diameter or less. If an abnormality is seen on an x-ray of the lungs that is larger than 3 cm, it is considered a “lung mass” instead of a nodule, and is more likely to be cancerous.

Symptoms of lung cancer Horner syndrome is a group of symptoms that may be a sign of lung cancer that is growing into the nerves found at the top of the lung. It is almost always caused by a non–small cell lung cancer. Symptoms include: severe shoulder pain; drooping or weakness of the eyelid or a smaller pupil in the eye

Bronchiectasis: Current Concepts in Pathogenesis, Immunology, and Microbiology Bronchiectasis is a disorder of persistent lung inflammation and recurrent infection, defined by a common pathological end point: irreversible bronchial dilatation arrived at through diverse etiologies. This suggests an interplay between immunogenetic susceptibility, immune dysregulation, bacterial infection, and lung damage.

Pulmonary Scarring May Increase Risk for Lung Cancer In the PLCO trial, pulmonary scarring was associated with increased lung cancer risk but only for cancer in the same lung where scarring was present, suggesting that scarring is associated with a localized process of tissue damage and repair that may contribute to cancer development.

Pulmonary fibrosis Pulmonary fibrosis (literally scarring of the lungs ) is a respiratory disease in which scars are formed in the lung tissues, leading to serious breathing problems.s a consequence patients suffer from perpetual shortness of breath. In some patients the specific cause of the disease can be diagnosed, but in others the probable cause cannot be determined, a condition called idiopathic pulmonary fibrosis.
