This complication can occur unexpectedly and without apparent trauma, particularly in patients on vitamin K antagonists.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation:<\/jats:title>\n                    <jats:p>A 60-year-old man presented to the emergency with acute dysphagia, dysphonia and a right-sided neck ecchymosis. The patient had been on vitamin K antagonists for 7\u2009years following a left intraventricular thrombus. Blood tests revealed an International Normalized Ratio of 7. The diagnosis of Spontaneous Retropharyngeal Hematoma was suspected given the absence of an identified cause and was confirmed by contrast-enhanced computed tomography. The hematoma was attributed to the patient\u2019s long-term use of vitamin K antagonists, which predisposed him to spontaneous bleeding. Treatment involved the administration of vitamin K but the patient ultimately passed as a result of respiratory arrest.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Spontaneous Retropharyngeal Hematoma due to VKA-related incidents is a rare but significant complication to consider in patients undergoing anticoagulant therapy.
