What do infiltrates in a CXR indicate?
When interpreting the x-ray, the radiologist will look for white spots in the lungs (called infiltrates) that identify an infection. This exam will also help determine if you have any complications related to pneumonia such as abscesses or pleural effusions (fluid surrounding the lungs).
What does infiltrate of lung mean?
From a pathophysiological perspective, the term “infiltrate” refers to “an abnormal substance that accumulates gradually within cells or body tissues” or “any substance or type of cell that occurs within or spreads as through the interstices (interstitium and/or alveoli) of the lung, that is foreign to the lung, or …
What is lingula of the lung?
The term lingula refers to the tip or tongue-like projection of the upper lobe of the left lung but in general it is considered also to be the entire portion of this segment which is supplied by the first segmental bronchus that arises from the upper lobe bronchus.
What is the function of lingula in lungs?
The lingula is not technically a lobe, but is the left lung equivalent of the right lung’s middle lobe. The hilium is the root of the lung and contains the structures involved in pulmonary circulation, as well as the pulmonary nerves and lymph vessels.
What are alveolar infiltrates?
Opacification of air spaces, caused by the filling of alveoli with blood, pus, or fluid. Alveolar infiltrates are seen on the chest radiograph as patchy areas of increased density, often surrounding air bronchograms.
What causes infiltrates in the lungs?
Pulmonary infiltrates commonly occur in the febrile neutropenic patient and have a number of causes, especially in the BMT recipient. These include non-infective conditions such as pulmonary edema, alveolar hemorrhage, adverse drug reactions, radiation injury and the idiopathic pneumonitis syndrome.
What is persistent pulmonary infiltrate?
Persistent pulmonary infiltrate results when a substance denser than air (e.g., pus, edema, blood, surfactant, protein, or cells) lingers within the lung parenchyma. Nonresolving and slowly resolving pneumonias are the most common broad categories of persistent pulmonary infiltrate.[ 1]
What is lingula disease?
The most common definition of MLS is recurrent or chronic collapse of the middle lobe of the right lung. Although originally described as occurring only in the middle lobe, the process can involve the lingula as well, which is sometimes called the lingula syndrome [5].
What is Lingular segment of left upper lobe?
The left upper lobe superior lingular segment is one of the four bronchopulmonary segments of the left upper lobe. It lies below the apicoposterior and anterior segments of the left upper lobe.
What is alveolar filling?
Alveolar diseases are characterized by filling of the alveoli with materials that impede its normal physiological function (ventilation). Alveolar diseases can be localized (focal) or diffuse. Names of the conditions depend upon the content of the material filling the alveoli.
What is acute alveolar disease?
Causes of acute alveolar lung disease include pulmonary edema (cardiogenic or neurogenic), pneumonia (bacterial or viral), systemic lupus erythematosus, bleeding in the lungs (e.g., Goodpasture syndrome), idiopathic pulmonary hemosiderosis, and granulomatosis with polyangiitis.
How many cases of lingular disease have been resected?
Of the 32 cases of lingular disease presented, 14 have been resected. The predominating disease was bronchiectasis. Carcinoma was encountered in four cases. Various other types of diseases have been seen in the lingular segment. If the patient’s condition warrants, we feel that resection is the treatment of choice in lingular bronchiectasis.
Can a lingular disease be diagnosed on a roentgenogram?
Various other types of diseases have been seen in the lingular segment. If the patient’s condition warrants, we feel that resection is the treatment of choice in lingular bronchiectasis. It is important to realize that lingular disease can be diagnosed on plain roentgenograms of the chest.
How is lingular disease diagnosed in the chest?
It is important to realize that lingular disease can be diagnosed on plain roentgenograms of the chest. On the posterio-anterior and lateral chest films one can suspect disease, and confirmation is possible by bronchoscopy, bronchography, or exploration. Lingular disease is present more often than is usually suspected.
What is the silhouette sign for lingular pneumonia?
You can utilize the silhouette sign to localize a pneumonia, even if only a frontal projection is available Lingular Pneumonia. The frontal view shows an airspace density in the left lower lung field (red arrow) which is silhouetting the left heart border (white arrow).
