Spontaneous retropharyngeal hematoma: An unusual presentation of thoracic aortic dissection

Airway obstruction by a retropharyngeal hematoma secondary to thoracic aortic aneurysm rupture

“…The clinical features and computed tomography findings in their case were very similar to the clinical features and computed tomography findings in our case [10]. According to their report, only one case with the same symptoms caused by a cervico-mediastinal hematoma due to aortic rupture had ever been reported [11,12]. Thus, because of the extremely rare clinical features of our case, it was difficult to determine the cause.…”

Aortic dissection presenting as pleural effusion

“…Other unusual presentations of aortic dissection with pleural effusion include a case of retropharyngeal haematoma7 and two cases of massive right-sided effusion 8…”

A case of acute upper and lower airway obstruction due to retropharyngeal haemorrhage secondary to acquired haemophilia A

“…High dose steroids were given at presentation and were continued until the inhibitor assay returned to normal. Other possible treatments include cyclophosphamide and intravenous immunoglobulin with steroid [10]; however, there is no firm evidence to demonstrate any improvement in efficacy with this approach [1,10].…”

“…Retropharyngeal haematoma is a rare cause of upper airway obstruction and is usually secondary to trauma, anticoagulation or more rarely aortic dissection [1]. Acquired haemophilia A is a rare autoimmune disorder that has not previously been described in the aetiology of retropharyngeal haemorrhage [2].…”
