Abstract

Spontaneous regression of a cerebral arteriovenous malformations (AVMs) is a rare and poorly understood phenomenon. We present a case of unruptured cerebral AVM in a patient presenting with intermittent headache. In order to reduce hemorrhagic risk, the patient underwent partial embolization of the AVM with Onyx glue. Follow-up digital subtraction angiography (DSA) showed complete obliteration of the residual AVM three months after the treatment. In conclusion, partial Onyx embolization of cerebral AVM may be an etiological factor of spontaneous regression. In order to reduce hemorrhagic risk, targeted partial embolization of the AVM may be an alternative treatment for some cases.
