Epistaxis (nosebleed) is very common and has a broad differential diagnosis in clinical practice. In clinical practice, anterior epistaxis are mainly located in Kiesselbach's plexus and posterior epistaxis (5% of all epistaxis) in Woodruff's plexus.
Epistaxis is very common, with a lifetime incidence of ~60% 2.
There are is a broad range of causes, both local and systemic 2:
- digital trauma (most common)
- nasal septal deviation
- neoplasms (rare)
- vascular malformations (rare)
- chemical irritants
They usually do not require imaging, unless they are very severe or recurrent. In rare instances, these can be evaluated in the interventional radiology suite for potential endovascular embolisation, especially if uncontrollable with nasal packing. Ideally, prior to embolisation, these cases should be imaged by head and neck CTA.
