Background The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which resulted in the worldwide coronavirus disease 2019 (COVID-19) pandemic of 2020, has particularly affected Latin America. Objective The purpose of the study was to analyze the imaging findings of pulmonary COVID-19 in a large pediatric series. Materials and methods Children with SARS-CoV-2 infection confirmed by either quantitative reverse transcription-polymerase chain reaction from nasopharyngeal swabs or presence of circulating immunoglobulin M (IgM) antibodies and who underwent chest radiograph or CT or both were included in this retrospective multicenter study. Three pediatric radiologists independently reviewed radiographs and CTs to identify the presence, localization, distribution and extension of pulmonary lesions. Results We included 140 children (71 female; median age 6.3 years, interquartile range 1.6–12.1 years) in the study. Peribronchial thickening (93%), ground-glass opacities (79%) and vascular engorgement (63%) were the most frequent findings on 131 radiographs. Ground-glass opacities (91%), vascular engorgement (84%) and peribronchial thickening (72%) were the most frequent findings on 32 CTs. Peribronchial thickening (100%), ground-glass opacities (83%) and pulmonary vascular engorgement (79%) were common radiograph findings in asymptomatic children ( n =25). Ground-glass opacity and consolidation were significantly higher in children who needed intensive care admission or died (92% and 48%), in contrast with children with a favorable outcome (71% and 24%, respectively; P <0.05). Conclusion Asymptomatic children and those with mild symptoms of COVID-19 showed mainly peribronchial thickening, ground-glass opacities and pulmonary vascular engorgement on radiographs. Ground-glass opacity and consolidation were more common in children who required intensive care admission or died.

Infections of the central nervous system (CNS) are a very common worldwide health problem in childhood with significant morbidity and mortality. In children, viruses are the most common cause of CNS infections, followed by bacterial etiology, and less frequent due to mycosis and other causes. Noncomplicated meningitis is easier to recognize clinically; however, complications of meningitis such as abscesses, infarcts, venous thrombosis, or extra-axial empyemas are difficult to recognize clinically, and imaging plays a very important role on this setting. In addition, it is important to keep in mind that infectious process adjacent to the CNS such as mastoiditis can develop by contiguity in an infectious process within the CNS. We display the most common causes of meningitis and their complications.
Background:The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus), which resulted in the worldwide COVID-19 pandemic of 2020, has particularly affected Latin America. Objective:The purpose of the study was to analyze the imaging findings of pulmonary COVID-19 in a large pediatric series.Materials and methods:Children with confirmed SARS-CoV-2 infection confirmed by either quantitative reverse transcription-polymerase chain reaction from nasopharyngeal swabs or presence of circulating IgM and/or IgG antibodies and who underwent chest radiograph (CXR) and/or computed tomography (CT) were included in this retrospective multicenter study. Three pediatric radiologists independently reviewed CXRs and CTs to identify the presence, localization, distribution and extension of pulmonary lesions. Results:One hundred and forty children (71 female; median age 6.2 years; interquartile range 1.6-12.1 years) were included in the study. Peribronchial thickening (93%), ground glass opacities (79%) and vascular engorgement (63%) were the most frequent findings on 131 CXRs. Ground glass opacities (91%), vascular engorgement (84%) and peribronchial thickening (72%) were the most frequent findings on 32 CTs. Peribronchial thickening (100%), ground-glass opacities (90%) and pulmonary vascular engorgement (74%) were common CXR findings in asymptomatic patients (n=20). Consolidation and ground-glass opacity were significantly higher in patients who needed ICU admission or expired, in contrast with patients with a good outcome (48% and 91%, vs 24% and 70% p<0.05, respectively).Conclusion:Asymptomatic children and those with mild symptoms of COVID-19 showed mainly peribronchial thickening, ground-glass opacities and pulmonary vascular engorgement on CXRs. Ground glass opacity and consolidation, were more common in patients who required ICU admission or died.
