Generally, the right middle and lower lung lobes are the most common sites affected, due to the larger caliber and more vertical orientation of the right mainstem bronchus. People who aspirate while standing can have bilateral lower lung lobe infiltrates.
median overall survival time of approximately 12–16 months, with five-year survival rate of approximately 26% and the long-term survival rate of approximately 4 - 5%. Limited-stage small cell lung carcinoma (LS-SCLC) is a type of small cell lung cancer (SCLC) that is confined to an area which is small enough to be encompassed within a ...
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
There are ten bronchopulmonary segments in the right lung: three in the superior lobe, two in the middle lobe, and five in the inferior lobe. Some of the segments may fuse in the left lung to form usually eight to nine segments (four to five in the upper lobe and four to five in the lower lobe. The delineation of the bronchopulmonary segments ...
In a clinical trial of 50 patients, a combination of olaparib and temozolomide in relapsed small-cell lung cancer yielded an overall response rate of 41.7%, median progression-free survival of 4.2 months, and overall survival was 8.5 months. [65] Lurbinectedin showed an increased overall survival rate in relapsed small cell lung cancer in a ...
During initial stages, this is most often found in the lower lobes, although involvement of the upper lobes and right middle lobe has also been reported early in the disease course. [ 16 ] [ 18 ] This is in contrast to the two similar coronaviruses, SARS and MERS , which more commonly involve only one lung on initial imaging.
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [1] [2] [3] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
A pulmonary infiltrate is a substance denser than air, such as pus, blood, or protein, which lingers within the parenchyma of the lungs. [1] Pulmonary infiltrates are associated with pneumonia , tuberculosis , [ citation needed ] and sarcoidosis .
