Diffuse alveolar hemorrhage in a pediatric patient with cri du chat syndrome: a case report

This case highlights a novel association between cri du chat syndrome (CdCS) and diffuse alveolar hemorrhage (DAH), a life-threatening pulmonary complication not previously reported in the literature. It emphasizes the importance of considering DAH in pediatric patients with genetic disorders presenting with recurrent hemoptysis and anemia. Early recognition, comprehensive evaluation, and multidisciplinary management are crucial for improving outcomes. This report expands the clinical spectrum of CdCS and urges heightened awareness among pediatricians and pulmonologists.
