[Stridor due to a subglottic hemangioma compressing the trachea].

Subglottic haemangioma can cause stridor in young children, and sometimes be life-threatening. Larynx ultrasound is a useful, non-irradiating screening test, but the diagnosis must be confirmed by bronchial fibroscopy and injected chest CT scan. Nowadays propranolol is the first-line treatment.
