- To know the incidence of necrotizing pneumonia in our health area in the last 5 years. - Describe the most relevant radiological findings for its correct diagnosis.
Necrotizing pneumonia is a severe and rare complication of an infectious respiratory process - community-acquired pneumonia (CAP).
It's described around 30-75% mortality. Bacterial is the most frequent etiology (S.
Fungus is less frequent and predominates in immunosuppressed patients. The most relevant risk factor mentioned in the literature is immunosuppression,
which can be aggravated by alcoholic and tobacco habits,...
Findings and procedure details
From 2013 to 2018 we diagnosed 20 cases of necrotizing pneumonia (13 male and 7 female). The average age of these patients was 66 years old. Only 5 of the total cases (25%) wereimmunosuppressed patients due to diabetes mellitus and neoplasia,
and 9 of the 20 cases (45%) were smokers. In relation to bacterial etiology,
the most frequent was S.
aureus and P.
aeruginosa but is important to describe that the most common result in the culture was negative. The most common location of...
- Necrotizing pneumonia is an uncommon but very serious complication of bacterial community pneumoniawith high morbidity and mortality. - Male smokers with some degree of immunodeficiency are the population at risk. - The pathogen responsible for this disease is seldom identified. -Most common chest-CT findings are consolidation with inner small low attenuation areas (air cavities,
sometimes withhydro-aerial levels),
pleural effusion and/or empyema.
