The retropharyngeal space is a rare site of spontaneous hemorrhage and the formation of a hematoma in this location is a rarer complication of therapy with anticoagulants. Nineteen cases of retropharyngeal hematoma have been reported in the literature, only two of which have been associated with anticoagulation therapy. ⋯ The complication was associated with a violent tussive episode. Airway obstruction necessitated a tracheostomy, and the persistent hematoma required external drainage.
