A spontaneous retropharyngeal haematoma: a suspected side-effect of indomethacin

Abstract

AbstractBackgroundRetropharyngeal haematomas are most commonly associated with trauma and anti-coagulant use. This paper describes the first reported case of a spontaneous retropharyngeal haematoma suspected to be due to indomethacin use.Case reportIt is proposed that the combination of indomethacin affecting platelet aggregation, alongside the patient coughing, may have led to this retropharyngeal haematoma.ConclusionThe complexities of management are discussed and the current literature reviewed. In the absence of airway compromise or a rapidly enlarging haematoma, patients can be managed conservatively with observation and close discussion with the haematology department. Follow-up imaging is not necessary if the patient's symptoms settle; however, any increase in parathyroid hormone levels must be investigated to exclude a parathyroid adenoma.
