Lint: spontaneous-retropharyngeal-haemorrhage

"It is particularly important to recognise that blood can result in diffusion-weighted imaging signal characteristics that can mimic pus, with high b=1000 signal and low ADC values encountered; this is important as a retropharyngeal abscess is a common differential diagnosis."

"Angiography and vessel embolisation may also be considered as an alternative and offers a number of advantages over surgical intervention; rapid access, short procedure time, ability to stem multiple sites of bleeding, ability to localise more superior origin of haemorrhage and a more selective therapeutic vessel occlusion not amenable to open surgery ⁸."

"There is no single consensus regarding airway management ³. The haematoma may distort the anatomy of the airway, creating a challenge in securing it safety ⁴. While prophylactic endotracheal intubation or tracheostomy may be tempting to secure the airway, such measures may exacerbate bleeding, especially in anticoagulated patients ³."
