An arteriovenous malformation (AVM) can occur in the tongue and may be associated with a number of clinical problems.

If the arteriovenous malformation is small then it is usually asymptomatic.


Conditions associated with clinically significant AVM:

(1) large in size

(2) multiple feeding arteries


Problems in management:

(1) poor delineation (poorly circumscribed)

(2) involvement of structures beyond the base of the tongue

(3) recurrence after initial resection



(1) airway obstruction

(2) hemorrhage with hemoptysis, which can be massive

(3) blood aspiration
