title: Large laryngeal vascular malformation in a 5-year-old child.
abstract: A 5-year-old boy was admitted with stridor, which was initially interpreted as subglottic laryngitis. He had a history of prolonged hoarseness and his voice was deep for his age. The stridor persisted despite treatment with epinephrine inhalations and intravenous glucocorticoids. A direct laryngoscopy and blood work up did not support the suspected diagnosis. A MRI was then carried out, followed by angiography. The latter revealed an arteriovenous malformation (AVM) involving the lingual and superior thyroid arteries bilaterally. Owing to the rareness and extent of such an AVM, the patient was referred to Paris for further treatment. This case presents the difficulties in diagnostics and emphasises the importance of diagnostics and multidisciplinary approaches with regard to treatment of AVMs.
