Nov 25, 2023 · Cavitating pneumonia is a complication that can occur with severe necrotizing pneumonia and in some publications, it is used synonymously with the latter term 2. It is a rare complication in both children and adults.

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.

In the case of infectious diseases, cavitation represents the outcome of complex interactions between host and pathogen. The focus of this review is to assist the clinician and clinical microbiologist in the evaluation of patients presenting with pulmonary cavities.

Oct 15, 2023 · Cavitary pneumonia is a form of lung infection that leads to the formation of cavities or hollow spaces within the lung tissue. These cavities are often filled with pus, inflammatory debris, or air. These pockets can be seen on imaging tests, and they are a critical aspect of diagnosis.

The wall thickness of the cavitary lung lesions in solitary disease can be useful in differentiating between benign and malignant disorders. A recent study found that a wall thickness of less than 7 mm was highly specific for benign disease, and a thickness of greater than 24 mm was highly specific for malignant disease.

Necrotizing pneumonia is a rare and severe complication of bacterial community-acquired pneumonia (CAP). Lying on a spectrum between lung abscess and pulmonary gangrene (1,2), necrotizing pneumonia is characterized by pulmonary inflammation with consolidation, peripheral necrosis and multiple small cavities .

Oct 2, 2023 · In a single-center study reporting on the radiographic appearance and clinical outcomes of 689 hospitalized patients with COVID-19 pneumonia, 3.3% of patients developed lung cavitation. Cavity sizes ranged from 30 to 100 mm in diameter and were solitary or multiple.

Oct 11, 2022 · Cavitary pneumonia raises the possibility of Panton-Valentine leukocidin (PVL) toxin-producing strains of MRSA. These strains are often community-acquired and extremely aggressive, causing necrotizing pneumonia among otherwise healthy individuals.

Mar 5, 2018 · To date, there are few specific guidelines published on the optimal approach to cavitary lung disease. 1,2 The intention of this review is to highlight the specific clinical, laboratory, and radiographic features that can help guide clinicians in their approach.

True cavities must be differentiated from their mimics, such as cystic disease, emphysema, infected bullae, and cystic bronchiectasis. The de and radiographic finitions appearances of these mimics that distinguish them from cavities are summarized in Table 1.5-8.
