The most common cause of a single lung cavity is lung cancer. [4] Bacterial, mycobacterial, and fungal infections are common causes of lung cavities. [5] Globally, tuberculosis is likely the most common infectious cause of lung cavities. [6] Less commonly, parasitic infections can cause cavities. [5] Viral infections almost never cause cavities ...
When a substance other than air fills an area of the lung it increases that area's density. On both x-ray and CT, this appears more grey or hazy as opposed to the normally dark-appearing lungs. Although it can sometimes be seen in normal lungs, common pathologic causes include infections, interstitial lung disease, and pulmonary edema. [2] [3]
A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules.
Lung abscess is a type of liquefactive necrosis of the lung tissue and formation of cavities (more than 2 cm) [1] containing necrotic debris or fluid caused by microbial infection. This pus -filled cavity is often caused by aspiration, which may occur during anesthesia, sedation, or unconsciousness from injury.
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma. Pneumatosis intestinalis, air or gas cysts in the bowel wall; Gastric pneumatosis (or gastric emphysema) is air or gas cysts in the stomach wall [6]
The invading organism starts multiplying, thereby releasing toxins that cause inflammation and edema of the lung parenchyma. This leads to the accumulation of cellular debris within the lungs. This leads to consolidation or solidification, terms used for macroscopic or radiologic appearance of the lungs affected by pneumonia.
A pulmonary contusion is another cause of bleeding within the lung tissue, but these result from microhemorrhages, multiple small bleeds, and the bleeding is not a discrete mass but rather occurs within the lung tissue. An indication of more severe damage to the lung than pulmonary contusion, a hematoma also takes longer to clear. [3]
