RT Journal Article T1 Neonatal pneumothoraces with atypical location: the role of lung ultrasound. A1 Gregorio-Hernández, Rebeca A1 Pérez-Pérez, Alba A1 Alonso-Ojembarrena, Almudena A1 Arriaga-Redondo, María A1 Ramos-Navarro, Cristina A1 Sánchez-Luna, Manuel K1 Case report K1 Lung ultrasound K1 Neonates K1 Pneumothorax K1 Ultrasound-guided procedure AB Neonatal pneumothorax (NP) is a potentially life-threatening condition. Lung ultrasound (LUS) has shown higher sensitivity and specificity in diagnosis compared to x-rays, but evidence regarding its usefulness in complex NP is lacking. We report four neonates suffering from cardiac or esophageal malformations who developed lateral and/or posterior pneumothoraces, in which LUS helped, making NP diagnosis and management easier and faster. LUS is an easy-to-use, fast, simple, and accurate tool when evaluating newborns with NP, also in atypical positions such as in surgical patients. • Lung ultrasound (LUS) has higher sensitivity and specificity than x-rays in the diagnosis of pneumothorax in neonatal patients. • This is the first report about neonatal pneumothorax in non-conventional areas (lateral/posterior) diagnosed by lung ultrasound and how obtaining this information is critical in order to optimize management.
