What is an infiltrate of the lung?
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 …
Are lung infiltrates normal?
Bilateral, diffuse pulmonary infiltrates are common. Radiographic abnormalities usually begin as interstitial infiltrates that progress to alveolar infiltrates.
Can a lung infiltrates be cancer?
In 8 of 13 instances with radiographic follow-up, the infiltrates assumed the appearance of round lesions or irregular masses. These observations suggested that the infiltrate is often a biologically earlier lesion than other radiographic forms of lung cancer.
What does infiltrate mean in medical terms?
Infiltration is the movement of cancer cells from their normal location into the surrounding non-cancerous tissue. Another word for infiltration is invasion. The movement of cancer cells to another part of the body is called metastasis.
What is the most common cause of a pleural effusion?
Transudative pleural effusion is caused by fluid leaking into the pleural space. This is from increased pressure in the blood vessels or a low blood protein count. Heart failure is the most common cause.
How long do pulmonary infiltrates last?
A good clinical response to pulmonary infiltrate is defined as 50% clearing of chest radiographic findings at 4 weeks of therapy. [7] Radiographic resolution of community-acquired bacterial pneumonia in the elderly.
What is the clinical significance of diffuse bilateral pulmonary infiltrates?
Acute respiratory distress syndrome is the clinical manifestation of severe, acute lung injury. It is characterized by the acute onset of diffuse, bilateral pulmonary infiltrates secondary to noncardiogenic pulmonary edema, refractory hypoxia, and decreased lung compliance.
Does infiltrate mean cancer?
Infiltration is the movement of cancer cells from their normal location into the surrounding non-cancerous tissue. Another word for infiltration is invasion. Infiltration is an important feature that pathologists look for when trying to decide if a tumour is benign (non-cancerous) or malignant (cancerous).
Can an infiltrate be cancer?
Cancer that has spread beyond the layer of tissue in which it developed and is growing into surrounding, healthy tissues. Also called invasive cancer.
What causes infiltration?
Infiltration occurs when I.V. fluid or medications leak into the surrounding tissue. Infiltration can be caused by improper placement or dislodgment of the catheter. Patient movement can cause the catheter to slip out or through the blood vessel lumen.
What happens during infiltration?
Infiltration is the process by which water on the ground surface enters the soil. Infiltration is governed by two forces, gravity, and capillary action. While smaller pores offer greater resistance to gravity, very small pores pull water through capillary action in addition to and even against the force of gravity.
