Pediatric Chest (2026)-W6-CPD0422-2026

Video Transcription

Video Summary

The transcript covers pediatric imaging of “marbles in the chest,” meaning multiple solid pulmonary nodules, and later expands to “bubbles,” chest wall lesions, and perinatal lung abnormalities. It organizes lung nodules into key clinical scenarios: metastatic disease in a child with cancer, septic emboli in a febrile child with cavitating nodules, invasive fungal infection in neutropenia with the halo sign, pulmonary vasculitis in chronic multisystem illness, and rare inflammatory causes such as Crohn-related necrobiotic nodules. It also reviews pulmonary AVMs, pseudonodules, and incidental nodules, emphasizing that management in children is case-by-case.<br /><br />The second section focuses on congenital and acquired cystic lung lesions in the perinatal period, especially CPAM, lung disease of prematurity/BPD, and air leaks such as PIE, pneumomediastinum, and pneumopericardium. The speaker highlights prenatal risk factors, postnatal evolution, and the importance of describing imaging features rather than overusing clinical labels.<br /><br />Finally, the talk tours pediatric chest wall pathology: normal variants, trauma including costochondral fractures, osteochondroma, fibrous dysplasia, Ewing sarcoma, chest wall infection, lymphatic disorders, rickets, and skeletal dysplasias. Overall, the key message is to use clinical context, recognize classic imaging patterns, and report findings that guide management.
