The aim of this study was to illustrate the chest radiographs (CR) and CT imaging features and sequential findings of cavitary necrosis in complicated childhood pneumonia. Among 30 children admitted in the Pediatric Intensive Care Unit for persistent or progressive pneumonia, respiratory distress or sepsis despite adequate antibiotic therapy, a study group of 9 children (5 girls and 4 boys; mean age 4 years) who had the radiographic features and CT criteria for cavitary necrosis complicated pneumonia was identified. The pathogens identified were Streptococcus pneumoniae( n=4), Aspergillus( n=2), Legionella( n=1), and Staphylococcus aureus( n=1). Sequential CR and CT scans were retrospectively reviewed. Follow-up CR and CT were evaluated for persistent abnormalities. Chest radiographs showed consolidations in 8 of the 9 patients. On CT examination, cavitary necrosis was localized to 1 lobe in 2 patients and 7 patients showed multilobar or bilateral areas of cavitary necrosis. In 3 patients of 9, the cavitary necrosis was initially shown on CT and visualization by CR was delayed by a time span varying from 5 to 9 days. In all patients with cavities, a mean number of five cavities were seen on antero-posterior CR, contrasting with the multiple cavities seen on CT. Parapneumonic effusions were shown by CR in 3 patients and in 5 patients by CT. Bronchopleural fistulae were demonstrated by CT alone ( n=3). No purulent pericarditis was demonstrated. The CT scan displayed persistent residual pneumatoceles of the left lower lobe in 2 patients. Computed tomography is able to define a more specific pattern of abnormalities than conventional CR in children with necrotizing pneumonia and allows an earlier diagnosis of this rapidly progressing condition. Lung necrosis and cavitation may also be associated with Aspergillus or Legionella pneumonia in the pediatric population

“…This entity includes exogenous lipoid pneumonia, which is caused by aspiration of nonvolatile and viscous hydrocarbon and usually presents at CT as areas of consolidation of low attenuation [2][3][4][5], and pneumonia following aspiration of volatile hydrocarbon, such as white spirit, which presents as acute pseudo infectious pneumonia [1][2][3][6][7][8]. The descriptions of the manifestations of acute hydrocarbon pneumonia have been limited to studies that included a small number of cases [6][7][8]. This report illustrates the early and sequential high-resolution computed tomographic (HRCT) findings of hydrocarbon pneumonia following attempted suicide (first described case) by tracking the initial coalescing masses of liquid densities followed by pneumothorax and pneumatoceles.…”

Acute hydrocarbon pneumonia after white spirit aspiration: sequential HRCT findings

et al. 2004

View full text Add to dashboard Cite

Hydrocarbon pneumonia is a very uncommon condition resulting from aspiration of mineral oil into the lung. We report the first description of early and sequential high-resolution computed tomographic (HRCT) findings of hydrocarbon pneumonia following attempted suicide by white spirit aspiration. Initial HRCT showed patchy opacities of coalescing masses with well-defined walls. They were visible in the middle lobe, lingula and lower lobes. Follow-up CT showed regression of the alveolar opacities, the presence of pneumatoceles and right asymptomatic pneumothorax. After 23 months of follow-up, the patient remained asymptomatic, and the follow-up CT scan was considered normal. The radiological features and a review of the relevant literature are briefly discussed.

“…Bray et al reported that turpentine aspiration induced a local inflammatory reaction in the terminal bronchi. In the acini and alveoli turpentine can induce tissue damageand loss of surfactant, along with intra-alveolar hemorrhage (21). In our patient, the tissue specimen obtained by transbronchial biopsy revealed multiple small eosinophilic vesicles surrounded by inflamma-Yanoet al tory cells (predominantly lymphocytes) in the bronchial submucosa.…”
