Cerebral arterio-venous malformations hemodynamics changes in hereditary hemorrhagic telangiectasia - case report.

BACKGROUND: Spontaneous obliteration of cerebral arteriovenous malformations (AVMs) is a rare phenomenon. Hereditary Hemorrhagic Telangiectasia (HHT) is a predisposal genetic condition for AVMs development in all organs. CASE ILLUSTRATION: We report the case of a 34 years old woman with HHT family history. After radiosurgical treatment of a symptomatic evolving cerebellar AVM, late control subtracted digital angiography (DSA) demonstrated the complete obliteration of this AVM but also spontaneous obliteration of 3 fronto-parietal AVMs without any hemorrhagic sign on MRI. CONCLUSION: To our knowledge, this is the first report of spontaneous obliteration of multiple and unruptured AVMs in a HTT case.
