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 Life support was withdrawn on day 30.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.

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

Filamin A (FLNA) is a widely expressed X-linked dominant gene that encodes Filamin A, a protein that crosslinks actin filaments and plays a crucial role in the structure of the cell cytoskeleton. With such a broad role, FLNA mutations are especially consequential and can result in cardiovascular malformations, intellectual disability, skeletal dysplasia, and neuronal migration abnormalities. Additionally, recent literature has linked FLNA mutation to pediatric-onset interstitial lung disease.
A three-month-old female with a history of atrial septal defect, patent ductus arteriosus, pulmonary valve dysplasia, micrognathia, and recent hospitalization for parainfluenza infection causing respiratory failure presented to the emergency department with worsening hypoxemia and respiratory distress. Initial chest radiograph demonstrated an interval increase in bilateral patchy opacifications suggestive of worsening multifocal infection. The patient was subsequently admitted. The patient’s clinical status failed to improve after multiple days of admission. A non-contrast CT study of the chest revealed multiple regions of air trapping, atelectasis, coarsened interstitial markings, and diffuse septal thickening, differential diagnosis included interstitial lung disease versus congenital alveolar abnormality. Of note, MR imaging of the brain obtained showed diffuse nodularity along the subependymal lining of the lateral ventricles and temporal horns, compatible with gray matter heterotopia. This prompted genetic testing which revealed Filamin A deficiency.
Filamin A mutation typically presents radiographically with hyperinflation of the lungs with scattered atelectasis, which can be complicated by concomitant pneumonia. This appearance can mimic pulmonary emphysema and bronchopulmonary dysplasia. Cardiac anomalies are a common manifestation of the mutation; notably, our patient had a history of a dysplastic pulmonary valve, ASD and PDA. CT imaging patterns vary and can present as a combination of cystic and diffuse ground-glass changes, hyperinflation, and emphysema. After extensive consultation, our patient transitioned to palliative care and ultimately passed away at 5 months of age. Maintaining a high index of suspicion for this rare but important entity is crucial to accurately diagnosing this inherited mutation, treating affected patients appropriately, and providing patients and their families with essential information regarding prognosis and inheritance patterns.
