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.
Thus, cystic lesions are unlikely to be cancer, while cavitary lesions are often caused by cancer. [3] In a study from 1980 that used chest X-rays to evaluate 65 cases of solitary lung cavities, 0% percent of cavities with walls 1 mm or less were malignant (that is, cancerous), versus 8% of cavities with walls 4 mm or less, 49% of cavities with ...
2. Any cavitary lesion - Lucency (darkened area) within the lung parenchyma, with or without irregular margins that might be surrounded by an area of airspace consolidation or infiltrates, or by nodular or fibrotic (reticular) densities, or both. The walls surrounding the lucent area can be thick or thin. Calcification can exist around a cavity.
The most common benign coin lesion is a granuloma (inflammatory nodule), for example due to tuberculosis or a fungal infection, such as Coccidioidomycosis. [6] Other infectious causes include a lung abscess , pneumonia (including pneumocystis pneumonia ) or rarely nocardial infection or worm infection (such as dirofilariasis or dog heartworm ...

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 ...
