Treated cerebral arteriovenous malformation causing radiation-induced vasculopathy

Case contributed by Dr Neil Rane

Presentation

History of right parietal AVM treated with radiosurgery six years ago.

Patient Data

Age: 60-65 years

1. Complete obliteration of the right parietal AVM.

2. Dominant ectatic right Sylvian M2 branch with a 6 mm aneurysmal ectasia at the M2 bifurcation. This branch has multiple beaded stenoses extending distally.

3. Similar albeit milder changes are evident within the ipsilateral parietal MCA and PCA branches.

Case Discussion

The appearance of vessels depicted in this case is extremely unusual and is most likely related to an AVM flow phenomenon with subsequent radiation-induced vasculopathy.

No saccular aneurysm in the Sylvian M2 trunk, but rather a fusiform dilatation.
