Respiratory malformation

Respiratory malformation is a broad grouping term used in the Orphanet classification (ORPHA:182111) to encompass a heterogeneous collection of congenital structural abnormalities affecting the respiratory system. These malformations can involve the upper and lower airways, the lung parenchyma, and associated vascular structures. Examples of conditions falling under this category include congenital pulmonary airway malformation (CPAM), bronchogenic cysts, pulmonary sequestration, tracheal agenesis or stenosis, laryngeal clefts, and congenital lobar emphysema, among others. Because this is a classification grouping rather than a single discrete disease entity, the clinical presentation varies widely depending on the specific malformation present. Symptoms may range from respiratory distress at birth, recurrent pulmonary infections, stridor, cyanosis, and feeding difficulties in neonates and infants, to incidental findings on imaging in older children or adults. Severity spans from life-threatening conditions requiring emergent surgical intervention to mild anomalies that may remain asymptomatic throughout life. Treatment depends entirely on the specific type and severity of the respiratory malformation. Surgical resection is often the definitive treatment for lesions such as CPAM or pulmonary sequestration, while airway malformations like tracheal stenosis may require reconstructive surgery or stenting. Supportive care including respiratory support, antibiotics for infections, and multidisciplinary follow-up are important components of management. Prenatal diagnosis via ultrasound and fetal MRI has improved early detection and planning. Because this Orphanet code represents a grouping category, patients should seek information specific to their individual diagnosis for the most relevant clinical guidance.
