Childhood interstitial (diffuse) lung disease (chILD) in infants consists of a rare and heterogeneous group of disorders previously classified with clinical, radiologic, and pathologic features. The purpose of this article is to discuss imaging techniques and provide a pattern-based approach for chILD in infants. Read More

Children’s interstitial lung diseases (chILD) comprise a large spectrum of rare diffuse lung disorders, with a subset of patients developing chronic fibrosing lung disease. While imaging criteria for lung fibrosis are established for adults and correlate with prognosis and outcome, there are limited data on imaging for diagnosis, prognosis, and outcomes in children with fibrotic lung disease. To fill this gap, a group of ILD specialists aimed to define the imaging features for diagnosis of lung fibrosis for a forthcoming randomized trial of nintedanib versus placebo in pediatric patients with fibrosing ILD (1199-0337; NCT04093024).

We report the case of a neonatal male with alveolar capillary dysplasia with misalignment of the pulmonary veins (ACD/MPV). ACD/MPV is a rare, fatal disorder of the development of the alveolar vasculature. In this disorder, alveolar capillaries are reduced in number and are improperly located within the walls of the alveoli impeding oxygen exchange. In addition to alveolar capillary abnormalities, there are other associated abnormalities with the cardiovascular, gastrointestinal tract, and genitourinary systems. In this report, we describe the case of a term male neonate with a prenatal diagnosis of hypoplastic left heart who developed respiratory distress shortly after birth. The patient required prolonged ECMO and underwent evaluation with CT angiography of the chest. CT findings included diffuse bilateral interstitial thickening with enhancing airspace disease scattered in the left lung. The respiratory distress continued to be unresponsive to treatment, with difficulty weaning ECMO and respiratory support. Life support was withdrawn on day 30. Pathologic examination at autopsy demonstrated ACD/MPV. Our case adds to the limited literature available in describing imaging findings of ACD/MPV and support for early diagnosis with lung biopsy as it can prevent aggressive futile interventions.

Down syndrome, typically caused by Trisomy 21, is the most common chromosomal abnormality resulting in intellectual disability affecting 1 in 600-800 pregnancies worldwide. Respiratory problems are the leading cause of hospitalizations and excess mortality in DS, accounting for 42% of admissions through age 2 years. Respiratory issues include pulmonary vascular disease, recurrent respiratory infection, sleep-disordered breathing, airway abnormalities, or subpleural cysts. Abnormalities like craniofacial anomalies, developmental delay, chronic aspiration, and hypotonia contribute to the severity of respiratory issues. Independent of congenital heart defect status, the lungs of DS children have widened alveolar ducts, and fewer and enlarged alveoli. These alveolar changes along with connective tissue abnormalities are believed to contribute to the development of subpleural cysts found in up to 20-36% of DS children. The clinical significance of these cysts is variable. It is important for radiologists to be familiar with subpleural cysts associated with DS as it may prevent misdiagnosis with other serious conditions. Additionally, subpleural cysts may increase the risk for pneumothorax or parenchymal damage during mechanical ventilation or surgery. Generally, subpleural cysts are poorly seen on radiographs and have been primarily identified using CT. We present a 5 year old male with DS, born at 36 weeks gestation, who presented to the emergency room with cough, rhinorrhea, and fever. He had no history of respiratory issues and received routine vaccinations. Chest radiograph revealed bilateral apical predominant subpleural cystic lucencies, perihilar fullness, and peribronchial cuffing. He was diagnosed with acute upper respiratory infection and discharged home with symptomatic management and outpatient follow-up. Sedated CT of the chest two weeks later had findings of diffuse bilateral subpleural and perilymphatic cysts, small subpleural calcifications, and mild scattered interlobular septal thickening. Since he did not have respiratory issues at baseline or after his illness, there was less concern for progressive disease requiring intervention and he was managed with conservative monitoring. Our case highlights the importance of recognizing pulmonary manifestations frequently associated with DS to improve disease recognition and prevention of complications. Read More

In this educational exhibit, we will present a series of childhood interstitial lung diseases (chILD) cases from our institution and present the x-ray and computed tomography (CT) images. We will describe a wide variety of pathologies that are encountered but are rare. We will discuss key imaging features and include teaching points of these chILDs. Read More

Ultrasonography is a very powerful non-invasive diagnostic tool widely employed for examining multiple organs and systems located both superficially and deeply. This is possible thanks to a wide range of transducers that work on different frequencies and sound lengths to explore all layers of anatomical structures. Nowadays, the reduction of exposure to ionizing radiation in children is advocated by the “as low as reasonably achievable” (ALARA) principle, and therefore, ultrasound (US) has become the main investigation tool in many assessments of lung pediatric disorders. The purpose of this educational exhibit is to describe the normal artefacts produced by LUS in a healthy lung to distinguish them from pathologic patterns and the application of LUS in pediatric diseases and procedures (ultrasound-Guided Lung Recruitment).
